GoTo Connect

GoTo Connect is a small business phone system with a cloud-based voice, video, and chat messaging app designed for smaller teams requiring scalable solutions but not especially advanced calling features.


GoTo Connect Business phone system


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.

Take a look at GoTo Connect’s drag-and-drop visual dial plan editor:


GoToConnect Dial Plan Editor


System administrators can create “utility nodes” according to agent schedules, preferred language, caller ID, call groups, and more. These nodes automatically shift according to call volume and agent availability, reducing missed calls and callbacks. With unlimited auto attendants and submenus, pre-made recording templates, and customizable greetings, call and personalized.

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.


GoTo Connect Plans & Pricing

GoTo Connect offers a free 14-day trial on an annual subscription. Their pricing for 2-10 users ranges from $22 to $43 per user per month.

GoTo Connect Pricing breakdown provides additional information.

  • Conference Phones: Yealink CP920 and CP960
  • Cordless Phones: Yealink W60P


Network Reliability And Customer Support 

Unfortunately, GoTo Connect’s customer support is consistently criticized by both past and current users because of difficulty connecting with live agents and slow turnaround times. Even its website chatbot doesn’t offer much quality assistance.

This is especially frustrating as GTC heavily advertises its alleged “24/7 support” but doesn’t specify that it’s only available to Standard and Premium customers.

Though GoTo Connect offers SSO and 2FA, it doesn’t provide end-to-end encryption. However, it has 10 global data centers to keep network performance consistent and SOC 3, CCPA, and HIPAA compliance.

What Users Like What Users Dislike
GoTo Meeting video conferencing included with every plan Lack of third-party software integrations, and included integrations are often too industry-specific to be useful to many users
Integration with 180+ desk phones let small businesses keep existing equipment Mediocre customer support, including a lackluster online knowledge base, means teams must be willing to “solve their problems”

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

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.


Dialpad Talk


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 on 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.


Dialpad Plans & Pricing

Dialpad offers a free 14-day trial. Their annual subscription prices range from $15 to $25 per user per month. Our Dialpad Pricing overview offers further details.

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.


Voange business phone system


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 needed. 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 levels. Vonage users can search transcriptions by keywords and can even connect them to their third-party CRM for additional data analysis.


Vonage Business Plans & Pricing

As of this writing, Vonage does not offer a free trial. Vonage Business Communication pricing for 1-30 users ranges from $19.99 to $39.99 per user per month. Our extensive review of Vonage Pricing offers more details.

  • Conference Phones: Poly Trio (8500, 8300, RealPresence Trio 8800 models), Yealink CP930W


Reliability And Customer Experience 

Vonage’s lack of adequate customer support is a common user complaint, with reviewers citing slow response time and the fact that Vonage makes it difficult for customers to connect with a live agent for billing questions.

Additionally, there is conflicting information on support hours. Though Vonage claims to offer 24/7 support, their website states that their live chat support team is not available on evenings and weekends, and that phone support is limited in the evenings.

Vonage is HIPAA, PCI, and GDPR compliant and uses AES 256-bit encryption. It has a 99.999% guaranteed uptime.

What Users Like What Users Dislike
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 General lack of onboarding support, requires customers to pay for specialized onboarding assistance

Zoom One

Zoom One is an all-in-one communication and collaboration tool combining Zoom Phone, Zoom Meetings, team chat messaging, 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.

Zoom is also celebrated for its huge number of third party-integrations and APIs.

In addition to 256-bit encryption, Zoom offers Single Sign-On, FEDRamp, SOC 2, GDPR, and HIPAA compliance. However, Zoom doesn’t offer (or at least publicize) a guaranteed uptime. However, its global points of presence and live systems monitoring page suggest high reliability.

Zoom One Customer Support is excellent, offering 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 and thriving user community allow for a high degree of self-service.

Large number of third-party integrations and APIs, plus frequent additions due to Zoom’s overall popularity Lack of a shared voicemail box for call groups can slow down the callback and resolution process
Advanced video calling features streamline remote team collaboration within a familiar, intuitive interface Phone call analytics need improvement, as of this writing, still limited compared to most providers

Ooma is one of the more basic small business phone systems on our list. Still, it’s a solid choice for companies that want to continue using their existing analog hardware, need an affordable cloud calling option, and want to avoid an extensive installation and setup process.


Ooma Office

Ooma is well-known for its mobile app, which is surprisingly robust for a more basic phone system.

Mobile users can transfer and flip phone calls from a softphone desktop app, send messages to groups, access voicemails, make international phone calls, connect with team members via in-app extension dialing and conference rooms, and update Ooma user preferences.

Ooma also automatically creates a virtual receptionist upon installation, which can be customized with text-to-audio menu options, language preferences, ring groups, call routing strategies, and different modes for after-work hours.

Reliability And Customer Experience 

Ooma offers 24/7 customer support via live chat, and phone support from Monday-Friday from 7:00 AM to 7:00 PM, and Saturday/Sunday from 8:00 AM to 5:00 PM.  It also includes a somewhat clunky online user knowledge base.

Ooma offers little insight into their network reliability and security processes, but it explicitly states that it is not HIPAA compliant and has “multiple connections” to Tier-1 international carriers.

Ooma does offer end-to-end encryption, but only when making calls to other Ooma users. Our research found that Ooma also doesn’t offer two-factor authentication.

Business Phone System 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 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 providers 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.


Landline Business Phone Systems 

Though standard landline telephones operating via the PSTN are still available as premises-based 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. Above all, standard phone systems are well 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 desk 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 phone systems are much more affordable than on-premise systems, as 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.

Our comparison of VoIP vs landlines offers additional information.



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.

Cloud 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:

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.

Our guide to Hosted PBX vs SIP Trunking further explains the differences between these two types of cloud-based business phone systems.


How to Choose a Business Phone System

Finding the right small 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 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 best Business VoIP providers for more information.


Small Business Phone Systems FAQs

Below, we’ve answered some of the top business phone system FAQs.

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
