What is a Business Phone System?

A business phone system is a VoIP-powered phone solution that provides unlimited calling, business texting, call recording, conference calls, and flexible internal and external business communications.

Cloud-based business phone systems include unlimited extensions, call flow options, and call management features that make it easy for customers to reach multiple departments, agents, or IVR menus via the same telephone number (though multiple business phone numbers are also available.)

This can make it challenging for business owners that want to incorporate Nextiva into existing software you may already be using. Be sure to check if integrations are available for your needs.
  • Mobile App Needs work: Nextiva’s mobile is not as comprehensive nor as feature-rich. It tends to be glitchy with notifications. We’ve also experienced login issues.

RingCentral Drawbacks

  • Pricing: RingCentral is more expensive than other business phone systems, which is especially an issue for smaller businesses with tighter budgets
  • Poor customer service:  We’ve experienced excessive hold times with RingCentral’s customer support, reaching over 10 minutes on hold. Reaching the right department typically required a transfer to another rep and more hold times.

3. Zoom

zoom logo

Zoom is an all-in-one communication and collaboration tool combining Zoom Phone, video meetings, team chat messaging, whiteboard, email, and collaboration tools in one system. Though a Free Plan is available, it doesn’t offer voice calling features and focuses primarily on video calling.

Most Zoom users typically switch to the unified communications plan from Zoom Meetings because they need more advanced business phone system capabilities. Therefore, the team collaboration features Zoom offers are generally the biggest draw.

Zoom One offers unlimited whiteboards, unlimited calling, 10 GB of cloud storage, and meeting capacities of up to 1,000 participants.

Even though Zoom Phone itself is a bit more basic than most options in this piece, it can integrate with virtually any CRM, project management, marketing, or workforce management tool, making it one of the most customizable business phone systems on the market today.


How Much Does Zoom Cost?

Zoom One Pro is available month-to-month starting at $15.99 per user or annually at $149.90 per user per license, representing up to 21% in savings.

  • Basic (Free): The free basic plan includes 40-minute video meetings with 100 attendees, 3 whiteboards, team chat, and some collaboration features like breakout rooms and automated captions
  • Pro ($15.99 monthly): Expands meeting time limit to 30 hours, supports 9 licenses, includes 5 GB of meeting recording per license, adds polling and co-hosting capabilities
  • Business ($19.99 monthly): Expands meeting capacity to 300 participants, provides unlimited whiteboards, supports 99 licenses, adds admin portal recording transcripts, meeting branding, and live language interpretation
  • Business Plus  ($25 monthly): Adds Zoom Phone features like VoIP, toll-free numbers, voicemail transcription, IVR, queueing, and call monitoring
  • Enterprise (custom pricing): Includes unlimited cloud storage, 500 to 1000-participant meeting capacity, webinar capabilities, and supports over 250 licenses

Check out our complete review of Zoom One pricing plans, which provides more pricing information.


What Sets Zoom Apart

  • Zoom is unique in its channel flexibility and pricing, since it offers Zoom Phone and Zoom One as separate products
  • Zoom Phone offers a business phone system with just VoIP and SMS, costing just $10 monthly, including a US or Canada-based number, which is ideal for small businesses
  • All Zoom Phone plans include auto attendants, call queueing, recording, and call center monitoring–features that some competitors reserve for advanced plans
  • Zoom One complements Zoom Phone well, as Zoom One offers a free version with team chat, whiteboards, document co-editing and video meetings hosting up to 100 attendees for 40 minutes


Why We Picked It

  • Zoom Customer Support is excellent. They offer all users 24/7 chat with a live agent. Though 24/7 phone support is available only for top-level plans, Zoom’s extensive online knowledge base and thriving user community allow ample self-service.
  • Large number of third-party integrations and APIs, plus frequent additions due to Zoom’s overall popularity
  • Advanced video calling features streamline remote team collaboration within a familiar, intuitive interface
  • Zoom Phone and Zoom One are great for companies that want an advanced business phone system with some multichannel collaboration features–at a budget price


Zoom Drawbacks:

  • Limited customization options: Zoom Phone’s interface is fixed, with limited options for customization. This can make it challenging for businesses with unique requirements to customize the plans to their needs.
  • Mobile app issues: We experienced a hard time connecting our Zoom phone calls to Airpods. The app had difficulty recognizing/transferring the audio to the already connected headset.
  • Zoom Phone requires a Zoom Video account: Zoom phone isn’t available as a standalone product, and you must have a Video account to add the Phone system
  • Time-consuming signup and setup process: In our attempt to set up a brand Zoom Phone account, receiving a quote via email took about two days, while with other competitors, we got a quote and phone number on our initial setup call in under an hour


Our Score for Zoom: 7.5/10

  • Most Zoom users typically switch to the unified communications plan from Zoom Meetings because they need more advanced business phone system capabilities. Therefore, the team collaboration features Zoom offers are generally the biggest draw.
  • Zoom does offer its phone system as low as $10/mo. However, it is a metered plan and does not offer unlimited calling.
  • Zoom is a no-brainer if you already use and love Zoom for video conferencing
  • Zoom offers many AI features and third party-integrations

4. GoTo Connect

GoTo Logo

GoTo Connect is a small business phone system with a cloud-based voice, video, and chat messaging app designed especially for IT teams requiring do-it-yourself scalable solutions.

GoTo Connect is best known for its Dial Plan Editor, popular for its overall ease of use and the advanced call routing and call flow strategies that can be set up in minutes.

System administrators can create “utility nodes” according to agent schedules, preferred language, caller ID, call groups, etc. These nodes automatically shift according to call volume and agent availability, reducing missed calls and callbacks.

GoTo Connect also includes call filtering tools that let users whitelist high-priority numbers so VIP clients avoid waiting on hold. These filters also automatically forward VIP calls to specific preset dial plans or extensions and reject blacklisted numbers.


How Much Does GoTo Connect Cost?

GoTo Connect offers two plans: the Basic plan costs $22 monthly per user, and the Standard plan costs $26 per user.

  • Basic plan ($24 monthly): Supports up to 20 users with VoIP calling, unlimited calls in the US and Canada, 40 monthly SMS credits per seat, video conferencing for 40 minutes with up to 4 participants, smart call routing, and 1 of each phone feature: auto attendant, dial plan, ring group, call queue
  • Standard plan ($29 monthly): Expands the unlimited calling area to 50+ countries and meeting capacity to 150 participants with no time limit, adds unlimited access to all phone features like call queues and ring groups

GoTo Connect cost breakdown provides additional information.


What Sets GoTo Connect Apart

  • GoTo Connect’s phone system is great for companies with high international call volumes because the Standard plan supports unlimited calling to over 50 countries–a larger unlimited calling area than any competitor
  • GoTo offers local, toll-free, and vanity numbers around the world
  • While the Basic plan only includes one call queue, auto attendant, and ring group, the Standard plan includes unlimited access to these features–making GoTo’s Standard plan the best option for call centers with a global presence


Why We Picked It

  • GoToMeeting video conferencing is included with every plan
  • Compatible with 180+ desk phones lets small businesses keep existing equipment
  • Offers native IT help desk ticketing solutions that seamlessly tie into the Voice and Video system


GoTo Connect Drawbacks

  • Expensive plans: GoTo Connect’s Basic plan costs $24 monthly per user–almost twice the cost of some alternatives’ cheapest plan
  • Limited Basic plan: GoTo’s Basic plan limits several key features–video meetings have a 4-participant capacity and 40-minute time limit, and the phone system only supports 1 auto attendant, ring group, and call queue. This forces larger teams to purchase the Standard plan, which is a pricy $29 monthly.
  • No live AI capabilities: While GoTo offers robust real-time analytics, it lacks some advanced AI-support tools competitors offer–like live transcription and speech support
    SMS credit: Each plan offers a preset number of SMS credit per user, capping how many texts a user can send without having to pay extra


Our Score for GoTo Connect: 7.2/10

  • GoTo Connect’s Standard plan offers an unlimited calling area with over 50 countries–a number that outperforms all competitors–making it a clear choice for companies with high international call volumes
  • The Basic plan is only suitable for small teams, since it caps video meetings at 40 minutes and 4 participants. This plan one offers 1 concurrent usage of key phone features, like an auto attendant and call queue.
  • The credit-based SMS structure makes GoTo a poor fit for teams that send a lot of texts, since some alternatives offer unlimited texting

5. 8×8

8x8 Logo

8×8 is a complete cloud PBX phone system offering unlimited local and global calling in 48 countries and SMS, MMS, team chat, Contact Center, and video meetings.

One of 8×8’s top features is its post-call survey tool, which includes IVR-powered questions that allow you to collect quick–but still valuable–feedback regarding agent performance.

These surveys can pose simple yes/no questions, ask for ratings on a scale of 1-10, and allow willing customers to leave more detailed voice recordings of feedback. Teams needing more conversation-based feedback can automatically transfer customers to dedicated post-call survey voice channels or call queues.

8×8 also includes a variety of programmable ring patterns, including round robin, sequential, simultaneous ring, and more. Ring group members can be re-ordered via a drag-and-drop menu, and admins can set the time before a call is forwarded to the next member.


How Much Does 8×8 Cost?

8×8 plans start at $28/user/mo on their X2 plan. This plan gives access to unlimited voice calling to 14 countries, HD audio and video conferencing, integrations, and more. 8×8 also offers a free 30-day trial, so you can test their phone system before committing to long-term contracts.

  • X2 plan ($24 monthly): Includes unlimited VoIP calling to 14 countries, team messaging and file sharing, call queues, multi-level auto attendant, video conferencing with 500 participants, live speech analytics, interactive meeting features like polls and hand raising, youtube live streaming
  • X4 plan ($44 monthly): Expands unlimited calling to 48 countries, adds advanced analytics and call monitoring with barge and takeover


What Sets 8×8 Apart

  • 8×8 offers a compromise between low-priced plans and international communication. The X2 plan includes a 14-country unlimited calling area, plus unlimited queues, multi-level auto attendants, live AI speech support, and call analytics.
  • While competitors like GoTo Connect offer a wider unlimited international calling area, 8×8 supports collaboration with up to 500 video-meeting participants, whereas GoTo only supports four participants on their Basic plan
  • 8×8 makes a good option for large teams, seeking collaboration tools on a budget, that make international calls within 8×8’s unlimited area


Why We Picked It

  • Advanced, AI-powered analytics, including Active Call monitoring, Company Summary, and Call Detail Records
  • Wide variety of Global calling options
  • 8×8 offers a 99.999% guaranteed uptime and has GDPR, HIPAA, CPNI, FISMA compliance, and TLS and SRTP encryption. The provider also has 35 global points of presence to keep the network running smoothly.
  • Extension-level call recording, on-demand or automatic call recordings and transcriptions


8×8 Drawbacks

  • International calling limitations: While 8×8 does offer wide international calling areas on both plans–14 and 48 countries, respectively–some of these countries exclude mobile numbers, a major downside. Companies should verify that their 8×8 plan supports mobile in the countries they call frequently.
  • Pricy plans: Like GoTo, 8×8’s cheapest plan is $24 monthly per user–double the cost of some alternative providers
  • Setup hassle: Many users have reported that the 8×8 app’s setup process feels unintuitive and lacks the ability to personalize the user dashboard


Our Score for 8×8: 7/10

  • While 8×8’s lowest-tier X2 plan costs more than alternatives, it works great for large teams because it has no user limit. X2 includes unlimited call queues and auto attendants.
  • 8×8 offers strong UCaaS collaboration with file-sharing in team chat, plus video meetings that include unique capabilities like instant polls and breakout rooms
  • Companies that host webinars, workshops, and demonstrations should favor 8×8 since it supports live streaming to YouTube for larger audiences

6. Dialpad

Dialpad Logo

Dialpad’s business phone system provides excellent value to businesses with high call volumes, specifically on mobile devices. It includes voice and video calling, team chat, virtual faxing, and SMS texting.

One of Dialpad’s top features is its AI-powered in-call voice assistance, Vi (short for “Voice Intelligence.”)

Vi offers real-time agent coaching, picking up potential action items and caller sentiment according to trigger keywords and phrases. When Vi “recognizes” something a customer says, it pulls up relevant information from the internal knowledge base, displaying vital information on the agent’s screen. This prevents agents from putting callers on hold, and increases first call resolution rates.

Users can also create Dialpad Departments, essentially more advanced ring groups. Departments are groups of agents that receive specific customer calls based on preset criteria. Each Department can contain up to 30 phone numbers.


How Much Does Dialpad Cost?

Dialpad offers a free 14-day trial. Annual subscriptions for the unified communications platform range from $15 to $25 per monthly user.

  • Standard plan ($15 monthly): VoIP with unlimited calling in the US and Canada, SMS, team chat with file sharing, video meetings with 10 participants and collaborative features like chat and virtual backgrounds, team chat with file sharing, AI-powered call and voicemail transcriptions, real-time analytics
  • Pro plan ($25 monthly): Adds local number availability in 70+ countries, 25 ring groups, CRM integrations, and supports multiple phone numbers per account

Our Dialpad cost breakdown offers further details.


What Sets Dialpad Apart

  • Dialpad offers an affordable multichannel communication platform for small companies seeking AI support and collaboration tools
  • Although video meetings are capped at 10 participants, they last 5 hours with a host of advanced features: chat, waiting rooms, whiteboards, and virtual backgrounds. All Dialpad plans include call recording, live speech coaching, real-time transcription, and automated summaries.


Why We Picked It

  • Dialpad offers a 99.9% uptime guarantee to all customers except those on the Enterprise plan, who have a 100% guaranteed uptime
  • With built-in network redundancy, number failovers, and automated data backups, Dialpad offers high reliability
  • Automated post-call notes and speech coaching help agents understand where to improve
  • Each plan includes call recording, call transcriptions, and custom routing options usually reserved for top-tier plans


Dialpad Drawbacks

  • Small video capacity: Dialpad meetings are full of dynamic features like chat, recording, and waiting rooms–but each plan only supports 10 participants per meeting. This limits productivity for large teams.
  • Limited integrations: Dialpad only supports integrations with 11 external applications. While these include popular software–like Microsoft Teams, HubSpot, and Salesforce–most UCaaS competitors offer many more options. Further, Dialpad’s lowest-tier Standard plan only features one integration–Google Workspace.
  • No international numbers on Standard plan: Users on Dialpad’s Standard plan can only purchase DID numbers in the US and Canada. To purchase international numbers, users must subscribe to the Pro or Enterprise plan.


Our Score for Dialpad: 6.5/10

  • Dialpad’s Standard plan offers great UCaaS value at $15 since it includes all core communication channels–voice, SMS, chat, video–with advanced features like file sharing, live call transcriptions, and AI support. Many competitors reserved these features for much higher price points.
  • While Dialpad provides great value for small teams, large teams may want another option because Dialpad meetings support only 10 participants, and the Standard-plan phone system only supports 3 separate ring groups
  • Teams seeking international business numbers will have to purchase the Pro plan

7. Vonage

Vonage Logo

Vonage offers two small business phone systems options: the unified Vonage Business Communication (VBC) suite or the basic mobile and desktop-only app that allows users to connect on the go.

Vonage’s Call Announce feature automatically plays customers’ responses to IVR prompts to agents before they connect to the customer. It prevents repetition and ensures the agent has the information to assist the caller.

Call tags, summaries of the customer’s issue, contact information, and more are played, allowing the agent to transfer the call to an agent with a more appropriate skill set. If an agent chooses not to accept the call, they can send calls to voicemail or reject it outright.

Vonage’s Conversation Analyzer is an AI-powered tool that uses NLP and Speech Analytics to transcribe conversations automatically, offering insight into support quality, call resolution speed, and customer satisfaction. Vonage users can search transcriptions by keywords and connect them to their third-party CRM for additional data analysis.


How Much Does Vonage Business Cost?

As of this writing, Vonage does not offer a free trial. Vonage Business Communication pricing for 1-30 users ranges from $14.99 to $39.99 per user per month.

  • Mobile plan ($19.99 monthly): VoIP with unlimited calling in the US, Mexico, and Canada, SMS, team chat, call queues, basic auto attendant
  • Premium plan ($29.99 monthly): Adds unlimited video meetings for up to 100 users with collaboration features like whiteboards and screen sharing, multi-level auto attendant, CRM integrations
  • Advanced plan ($39.99 monthly): Adds 15 hours of call recording, ring groups, and video voicemail with transcription

Our extensive review of Vonage Pricing offers more details.


What Sets Vonage Apart

  • Vonage’s Mobile plan offers a well-rounded VoIP phone system for companies that don’t want video–just voice, SMS, and internal team chat in an easy-to-use desktop and mobile app. For those who do want video, Vonage’s Premium and Advanced plans support up to 100 meeting participants.
  • Vonage offers a few unique add-ons, most notably their Business Inbox feature that combines all of an agent’s messaging channels into one cohesive list. Agents can respond to customers across digital channels with a few clicks, keeping it all organized in one place.


Why We Picked It

  • Vonage is HIPAA, PCI, and GDPR compliant and uses AES 256-bit encryption. It has a 99.999% guaranteed uptime.
  • On-demand, company-wide, and automatic call recording rules store up to 15 hours of audio/video per extension and allows admins to email recordings or play them directly in the Admin Portal
  • High scalability thanks to add-ons like Visual Voicemail, Call Queuing, Call Recording, Call Monitoring, Call Groups, and more
  • Offers a mobile-only plan starting at $10/mo


Vonage Drawbacks

  • Lacks advanced features: Vonage Unified Communications only includes basic business phone system features, like auto attendants and call queues. It lacks tools like file sharing, AI support, call monitoring, and analytics.
  • Call recording as an add-on: While many alternatives include automatic call recording as a built-in feature, Vonage offers recording as an add-on at $4.99 monthly per user
  • Key features are overpriced: Video meetings and multi-level auto attendants are only included with the Premium plan, costing $29.99 monthly per user. Many competitors include these features in their basic plan for half Vonage’s price.


Our Score for Vonage Business: 6/10

  • Vonage Unified Communications does include basic UCaaS features, but many of them require the $29 Premium plan which is overpriced compared with other platforms
  • Vonage video meetings offer engaging features like whiteboards and chat, but they are limited to 100 users and lack advanced collaboration tools that competitors offer–like polls and breakout rooms
  • The phone system includes call queueing on all plans, which is a useful feature some competitors don’t have

Business Phone System Essential Features

Though there are over 100 VoIP phone system features, we’ve highlighted the most important features for small businesses below:


Call Routing

Call Routing is a business phone system feature that automatically distributes calls to specific agents, ring groups, departments, or voicemail boxes according to preset rules and/or responses to IVR prompts–without putting the customer on hold or forcing them to hang up call another number.

Call Routing

Popular call routing strategies include list-based routing, skills-based routing, VIP/relationship-based routing, time-based routing, most idle routing, and round-robin routing.


Call Forwarding

Call Forwarding automatically sends (forwards) unanswered calls to additional business telephone numbers instead of sending them to voicemail, ending the calls, or making customers call additional phone numbers themselves.

For example, if you miss a call at your desk phone, call forwarding will instantly forward the call to your mobile phone. If you don’t answer on your cell, the call is forwarded to your home phone, your voicemail box, another agent, or the main menu. Call forwarding settings can be customized and edited at any time, and admins can set the number of rings before the call is forwarded to the next number on the list.


Omnichannel Communication

Omnichannel customer service and communication combine all your business communication channels (video, calling, SMS, etc.) into one unified, automatically-synced interface.

Omnichannel Customer Service

Customers and employees can easily switch between channels during a single conversation or support interaction without missing a beat. For example, a customer could start a customer support interaction with a phone call and end that interaction on a video conference with screen sharing for better assistance.

Omnichannel communication not only cuts down on app switching, it also lets customers choose their preferred way to connect with your company. Plus, it makes it easy for multiple reps to work on the same support ticket without the customer needing to repeat themselves each time they speak to a different agent.


Visual Voicemail

Visual Voicemail automatically transcribes voicemail messages, then sends these transcriptions to agents as emails, text messages, or displays the text directly in the softphone interface.

This way, agents don’t lose time listening to longer messages, can better prioritize callbacks, or send reply texts to callers they’ve missed with relevant information.


Automated Callbacks

Automated Callbacks (also called Customer Callbacks) let customers select their preferred date and time to receive a callback from a business, allowing them to avoid waiting on hold for extended periods or having to call back multiple times until they reach an agent.

Once the customer schedules their callback, the call is automatically placed in a relevant agent’s call queue, speeding up the resolution process and keeping customer satisfaction rates high by reducing hold times.



Third-party integrations allow small businesses to connect existing software and other applications they’re currently using to their business phone system, eliminating the need to switch between windows to access multiple tools.

Integrations make it easy for teams to access additional features that the VoIP provider may not offer, while APIs let IT teams customize their own features and apps to integrate with their phone system.

Common third-party integrations include marketing tools like MailChimp, chat apps like Slack, project management apps like Asana, CRM software like Salesforce, and industry-specific apps like Canva, Curve Dental, or Shopify.


Interactive Voice Response (IVR) 

IVR is an interactive call menu that automatically plays when a customer dials your business phone number, providing prompts and information that allows for a higher level of customer self-service.

IVR Call Flow

Callers can enter their responses to IVR system prompts via dial pad touch-tone or speak their responses into the phone directly. NLP (Natural Language Processing) and editable call flow paths analyze the customer’s response, sending calls to relevant agents and departments or playing helpful pre-recorded information.


Call Recording and Call Monitoring

Call recording records all business calls automatically or on-demand, saving these recordings in a searchable database that lets managers conduct quality assessments, review call histories, and protect themselves in the event of a false accusation by a client. Many recording tools allow agents and admins to pause and restart recordings during conversations, protecting clients’ most sensitive information.

Most call recordings are also transcribed, allowing faster call reviews and letting managers search for specific words/phrases or review detailed voice analytics.

Call monitoring lets managers listen to agent conversations with clients in real-time, while call whisper lets managers advise agents during live conversations (without the caller hearing.) Call barge (call takeover) lets managers immediately take control of any customer-client call that needs a higher-up’s intervention.


Call Reporting and Analytics

Small business phone systems offer customizable and pre-made reporting templates that offer insight into customer and agent behavior, call center and contact center activity, and even AI-powered analysis.

These reports can be generated automatically or manually and shared and exported to other team members.

Common metrics to track include:

  • Daily/weekly/monthly call volume (total number of business calls, calls per department, calls per agent, calls within a specific date range, etc.)
  • Outbound Calls: Incoming Calls ratio
  • Percentage of missed calls transferred calls, and calls that went to voicemail.
  • Call Abandonment Rate
  • Cost per Call
  • Average call length
  • Customer Satisfaction Rating (CSAT)
  • First Call Resolution Rate (FCR)


Types of Business Phone Systems

Here, we’ll explain the available types of business phone systems, focusing especially on the differences between premise-based and cloud-based solutions.


Premise-Based Phone Systems 

An On-Premise (Premises-Based) business phone system means all necessary telephony equipment and hardware (servers, handsets, wiring, etc.) are physically located on the business or office premises.

It also means the end user (AKA, your company) is responsible for managing business phone system installation, upgrades, maintenance, and security–not the phone system provider themselves.


Traditional Phone and Landline Phone Systems 

Though standard landline telephones operating via the PSTN are still available as premises-based office phone system solutions, most companies have made the switch to on-premise PBX systems.


Because not only do old-school landlines and cordless phones lack the features of cloud-based VoIP phone systems, but they’re also incredibly expensive to operate and don’t cater to the business needs of most companies. Above all, standard phone systems are on their way to becoming entirely obsolete–with most experts estimating they’ll be mostly gone by 2025.


Traditional PBX Systems 

Like landlines, Traditional PBX (Private Branch Exchange) also uses the PSTN to manage inbound and outbound business phone calls.

However, an on-premise PBX essentially provides your business with its own private telephone data network, meaning you’ll cut down on the costs of additional phone lines.

Although this offers your company greater control, note that a standard PBX phone system is fixed to a single location (within your office building, where the hardware is located.

It’s also accessible only to connected devices, like IP phones–so agents can only use their business telephones when they’re physically at the office. Finally, the sheer expense of an on-premise PBX system, which can easily run up to $20,000 to install, means it’s just not an option for small businesses.


Cloud-Based Phone Systems 

A cloud-based phone system uses Internet-powered VoIP (Voice over Internet Protocol) to offer provider-managed business telephone communications hosted offsite, within the virtual cloud.

Cloud business phone systems are much more affordable than on-premise systems. They can work with existing equipment, don’t require in-house IT teams since the provider manages maintenance and upgrades, and offer scalable month-to-month bundled payment plans. Most companies switching from landlines to virtual phone systems save at least 50% on business communications costs.



Because VoIP (sometimes called virtual telephony or IP telephony) isn’t connected to the wired PSTN, your business phone system is accessible anywhere and on any device with an Internet connection. This means agents can take calls on their desktop computers via a softphone interface, on mobile phones via iOS or Android mobile apps, or on tablets.

VoIP phone systems offer flexibility, scalability, and the incalculable benefit of numerous advanced VoIP service features–all for a fraction of the cost of premises-based systems.


Cloud PBX Systems

Cloud PBX (Hosted PBX or Virtual PBX) phone systems also provide businesses with their private phone system. However, unlike on-premise PBX, cloud PBX is hosted in an offsite data center and managed by the third-party PBX provider, not the end user.

This means businesses avoid the expenses of purchasing hardware, in-house IT teams, and maintenance. Hosted PBX makes it much easier to scale phone lines up or down, as it doesn’t require the installation of physical wiring and cabling.

Best of all, Cloud PBX systems give users access to VoIP business phone systems’ mobility and advanced features. Our overview of Virtual PBX phone systems provides additional details.


SIP Trunking

SIP Trunking is a gateway that establishes a connection between your existing premise-based PBX system and VoIP virtual telephony, allowing you to simultaneously keep your on-site PBX equipment and get the benefits of VoIP.

The below diagram offers a visual explanation of the differences between hosted PBX and SIP Trunking:

Hosted PBX vs SIP Trunking

SIP Trunk users are still responsible for purchasing and maintaining their own PBX equipment. However, SIP Trunking creates a virtual connection to the PSTN that makes adding virtually unlimited phone lines and communication channels much easier–while combining all telephony solutions in one structure.


Choosing a Phone System for Your Business

Finding the right business phone system shouldn’t just be about pricing and available features. Here are some points to keep in mind:

  • Consider smaller details like contract lengths, guaranteed uptime, support channels and availability, and overall ease of use
  • Think about how long your team will take to adapt to and learn to use the potential phone system provider and whether or not on-demand video or in-person user training is offered.
  • Remember to ensure that the platform is compatible with any hardware/equipment you plan to continue using, as well as with your preferred third-party software.

Above all, do your research and don’t rush into a decision. Once you’ve narrowed your list, check our head-to-head comparisons on the business phone systems mentioned in this article for more information.



Below, we’ve answered some of the top FAQs related to business phone systems.

A business phone system works by facilitating VoIP communication, which breaks up voice audio into smaller data packets that travel to their destination via the Internet, where they then reassemble. VoIP phone systems make it easy to add new phone numbers and extensions, as no physical copper wiring is required. VoIP telephony means scalable, mobile calling anywhere with Internet access.
Most business phone systems require little installation and work with your existing hardware (desktop computers, smartphones, etc.) You’ll need a strong Internet connection, a router, a modem, and a few other key pieces of VoIP equipment. The setup process of the system itself usually entails developing call flow paths, recording IVR systems, assigning agents to extensions and call groups, and more.

Top business phone system benefits include:

  • Cost savings of between 50-70% compared to landline phone systems
  • Additional communication channels
  • Advanced VoIP features like visual voicemail, IVR, and automated callbacks
  • More detailed real-time and historical analytics
  • Improved internal collaboration
  • Higher first call resolution rates
The two main types of business phone systems are on-premise and cloud-based, with the latter being the most popular. The most common cloud phone types are: - VoIP - SIP Trunking - Hosted PBX
