In this article, I'll provide a step-by-step guide to help you confidently find and compare the best business phone system for your particular needs. From assessing your business needs to comparing features and pricing and even considering factors such as integrations and security, I've got you covered.

So, let's dive in and discover how to choose the best solution.


Choosing a Business Phone System

Here are the steps to choose the best solution for your company:


Step 1: Determine Business Needs

First, note your current business phone system’s shortcomings and create a list of business needs – features and qualities for your ideal phone system.

When outlining  business needs, consider the following:

  • Current phone system shortcomings: What friction points and inefficiencies do you experience? Do you need to use multiple apps? Try to get a feel for your phone system's friction points.
  • Current phone system usage: Analyze your current call volume, including the times of day and weekdays that you receive or make the most calls. Note your frequent calling destinations–and if they’re inside or outside the US.
  • Business size: Note how many agents you have, where they’re located, and your team’s remote, in-person, or hybrid status. Consider where your agents work–home, coffee shop, office–and if they need an office phone system with a strong mobile app, or call flipping for on-the-go handling.
  • Expenses: Record what your current phone system costs you per month, in total, for all users. Generate an average per-user cost.


Step 2: Identify the Features and Channels You Need

After identifying your phone system’s friction points and areas of need, specify the features and channels most important to you.

Consider the following features and channels:

  • Communication channels: While VoIP and SMS texting might be all you need, your agents may also benefit from collaboration-focused channels like team messaging and video conferencing. Usually, these features come built-into a VoIP phone system.
  • Routing features: If you have a complex phone system with multiple departments and specialties–prioritize IVR, call queueing, ring groups, and automatic call distribution (ACD) with skills-based routing
  • Analytics and monitoring: If your team has a lot of agents, or if your supervisor feels overwhelmed, choose a business phone system that offers advanced real-time analytics and call center monitoring–with listen, whisper, and barge
  • Collaboration tools: To facilitate team communication, choose a business phone system that offers file sharing and interactive video features like whiteboards, breakout rooms, and polls
  • Phone number availability: Some VoIP providers offer virtual phone numbers based inside the US, while other providers offer business phone numbers from around the globe.
  • Unlimited calling area: Most office phone systems support unlimited calling within the US and Canada. However, some providers and plans include expanded unlimited areas with dozens of countries–while some offer this as an add-on. If you frequently make international calls, opt for a provider with a larger unlimited calling area.


Step 3: Set a Budget

A VoIP phone system typically costs between $15 and $35 monthly per user. Note the cost of your current phone system per month and use this as a guide to determine your monthly budget.

Keep in mind that VoIP includes dozens of additional features that will replace some of the apps you currently pay for.


Step 4: Compare Features and Pricing

Once you have outlined your budget and desired features, compare each VoIP provider’s offerings. Since most providers offer two or three subscription tiers, note the significant features that each tier adds.

Aim to find a plan that not only fits your budget but provides optimal value–including your must-have channels and features, with few excess features that you likely won’t use.


Step 5: Utilize Free Trials and Tutorials

Utilize free trials from your top phone system choices, asking agents afterward about their experience with each platform. YouTube demos and tutorials provide a valuable VoIP resource, showcasing each VoIP software’s interface, collaboration tools, analytics, and routing setup.

Use free trials and tutorials to research the following:

  • Interface: The app’s interface should be spacious and intuitive for you, with channels and tools available in just a few clicks
  • Menu: Ensure that the app’s menu makes sense to users, with menu tabs for key items like Calls, Contacts, Messaging, and Settings. Notification pings should be easy to spot, for new tasks and messages.
  • On-call dashboard: Get a feel for the agent’s experience live on-call. Practice transferring calls, viewing the queue, and using call monitoring.


Step 6: Consider Additional Factors

  • Value and pricing structure: Does the provider offer pay-as-you-go or bundled voice call minutes, tiered plans or a la carte add-ons, a free trial, contract-based or volume discounts?
  • Available integrations: Is the cloud phone system compatible with any third-party platform you’re using now or plan to in the future? Are APIs available?
  • Security and reliability: Does the platform have an SLA-guaranteed 99.9% minimum uptime, global points of presence, automatic data backups, backup power sources, and real-time service alerts? Is it HIPAA, PCI, GDPR, and SOC 3 compliant? Does it offer SSO, meeting passwords, and 24/7 network monitoring with end-to-end encryption?
  • Customer support: Is 24/7 customer support available, and if so, on what channels? How long does it take customer service to respond to and resolve an incident? Is paid priority support available?


Essential Features to Know

Though there are over 100 VoIP features, we’ve highlighted the most important ones 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.

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 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.

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 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.

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.

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

Most 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

Below is the overview of the main types of business phone systems.



Landline phones systems use the public-switched telephone network (PSTN) to send an analog audio signal from caller to recipient. Landline phone systems require that phones are physically connected to the PSTN.

While landline service is reliable, it has a few drawbacks. For one, the telephony is noticeably slower than VoIP, and the audio quality is lower. Further, each landline phone number is fixed, which means that your business can only use numbers that are physically rooted to your address and local area code.



Voice over Internet Protocol (VoIP) phone systems make phone calls over the Internet, rather than landline cables. Instead of landline’s analog signal, VoIP transmits voice via audio data packets, which travel from the caller's network through the VoIP provider’s server, to the call recipient.

VoIP providers typically offer service through a VoIP, which users can access and use to make calls via desktop, mobile, or browser. Cloud-based calling is typically included within virtual phone systems, unified communications (UCaaS) platforms, and call centers.

Compared to landline, VoIP phone systems offer several benefits:

  • Better audio quality
  • Faster sound transmission
  • Mobility via computer and mobile-based calling
  • Virtual phone numbers based anywhere in the world
  • Scalability


On-Premise PBX

On-premise private branch exchange (PBX) is when your company hosts all phone system hardware onsite, in your company office. This means you manage your phones, VoIP servers, wires, and potentially a SIP trunk that connects your VoIP system to the PSTN.

While on-premise PBX systems grant greater control over your VoIP operations, they require frequent IT maintenance and can be costly, compared to cloud-hosted solutions.


Hosted PBX

A cloud-hosted PBX system is when your VoIP service provider manages all the servers and data centers required for digital telephony. As the user, all you need is an Internet connected device and a router. Your hosted PBX provider offers an app, through which your business users can make and receive calls from any device or browser.

Hosted PBX systems tend to be the most popular type of VoIP setup because they’re low-maintenance. Since hosted PBX saves your IT team headache and hours of upkeep, hosted PBX is generally more cost-effective than hosting your own on-premise VoIP system.


Benefits of a Cloud Business Phone System

  • Cost savings: Free/unlimited local and long-distance calling, affordable international calling, flexible pay-as-you-go pricing or volume/committed use discounts, doesn’t require expensive premise-based equipment, provider handles ongoing maintenance, advanced features increase first call resolution (FCR) rates and lower cost per call
  • Mobility and flexibility: Ideal for remote/blended teams, cloud phone systems are accessible on any device with an Internet connection. Agents can take calls on their preferred devices from any location and switch devices during active calls
  • Quick setup process: Businesses can use existing equipment, port in existing business phone numbers, and add users/features with a few clicks. Cloud phone system providers offer onboarding, training webinars, and custom setup processes if needed
  • Improved customer satisfaction: Call management features eliminate or reduce call hold times and connect customers to the best available agent, IVR/virtual receptionists provide 24/7 customer self-service, CRM integrations and call notes empower personalized customer service
  • Increased productivity: Workflow automation, auto dialers, call recordings/transcriptions, real-time team collaboration, meeting summaries, and agent assist eliminate time-consuming manual tasks and decrease the margin of human error
  • Ease of use: Quick installation and setup process, intuitive and customizable agent dashboards, on-demand or custom software training webinars


Challenges and Limitations of Cloud-Based Phone Systems

  • Requires sufficient bandwidth: A VoIP call requires about 300 Kbps of bandwidth to ensure strong sound quality. If your local network has too much traffic or a poor internet connection, you may experience jitter, latency, or dropped calls.
  • Learning curve with new features: Some users familiar with an old phone system may face a learning curve when adapting to cloud-based VoIP software. Many cloud phone systems include a dashboard interface and advanced call controls. While these are valuable tools, it may take a few weeks for staff to adjust.
  • Hidden fees: A VoIP system’s monthly cost usually includes not only the subscription itself but some additional taxes and fees that can add several dollars monthly per user.
  • Setup confusion: Some companies struggle to get new users set up with phone numbers. Occasionally, a user’s phone will automatically send calls to voicemail, or fail to ring in response to an inbound call. Some administrators also struggle to create queues and IVR menus.
  • Hacking vulnerability: While VoIP services encrypt call data and are generally quite secure, VoIP calls and cloud-based phone systems can be vulnerable to hackers and other online threats.
  • Harder for emergency services to locate: Since cloud-based phone system phone numbers aren’t linked to a physical address, it’s harder for emergency dispatch services like 911 to track a user’s location when the user calls.
