The Best Business Phone Systems for External Communication

Most businesses primarily use their phone systems for external communication, like answering customer phone calls or reaching out to vendors. Reliability, security, and easy setup are essential considerations here. 


Nextiva logo

If security is your priority when handling communications between your company and clients, Nextiva is a top contender. Every call gets TLS + SRTP encryption, and Nextiva’s phone service, call recording, faxing, and video conferencing are HIPAA-compliant. 

You also can’t go wrong with all the additional features you get from a Nextiva business phone system. From call queuing and screening to setting up a fully automated call flow with a virtual attendant, Nextiva makes things easier for your team to engage with and please customers, clients, and vendors.

As a bonus, Nextiva’s easy-to-use administration lets anyone on your team work on the platform, tweak their settings, or even install new lines or equipment if needed. Nextiva allows for simple expansion of your phone system, too, with free number porting, the ability to bring your own device, and available equipment rentals.

RingCentral logo

RingCentral provides fantastic call management, with all plans including call transferring, screening, logs, forwarding, and answering rules. Higher-tier plans add shared lines and a multi-level auto-attendant on top of that. Together, those features help your team make and field more calls with better service. 

RingCentral’s business phone system is also known for its friendly interface. Thanks to its intuitive design that simplifies setup and operation, your team can spend less time figuring out features and more time remaining productive, whether that entails qualifying leads, coordinating with clients, or solving customer problems.

We also appreciate that RingCentral includes call logs on each plan, giving your team detailed reporting of inbound and outbound calls. That helps a lot with improving the quality of your external communications through coaching, forecasting, and tracking.

Microsoft Teams

Microsoft Teams logo

Use Microsoft Teams to ensure that customers connect to the right members of your team. Beyond just auto-attendants and IVR (both of which Teams offers standard), the service’s busy-on-busy feature lets you decide how to handle calls when a number or extension is busy, such as forwarding the call to another number.

Sales and support teams will especially find the call transferring options useful. From a call, representatives can choose the Consult and Transfer feature to first consult with the person they’d like to transfer the call to. The rep who took the call initially can brief their teammate to prepare them for their upcoming call.

If your team consults with customers or clients via video, they’ll find the reliability and quality of Microsoft Teams’ video conferencing virtually unmatched, even with low-quality internet service connections on either end.

Google Voice

Google Voice logo

Companies that regularly use Google’s tools might prefer Google Voice for their business phone system. It connects to Gmail, Google Meet, Google Calendar, and more through your Google Workspace account without any additional equipment or software setup needed.

It’s important for us to note that Google Voice does not provide toll-free numbers at all, and international numbers are only available for an extra cost. However, this won’t be a concern for domestic-only businesses. If you’re small enough to be running your operation on Google Workspace, you’re likely to get everything you need for external communication from Google Voice.

On this platform, your team can transfer calls, block callers, customize routing options, and turn on an auto-attendant when necessary. Text messaging is also available over WiFi for no extra charge when texting numbers in the United States and Canada.

Read our comprehensive guide to Google Voice to learn how it works.


Twilio logo

Twilio delivers a unique feature known as masked calling that hides the numbers of both parties on a call, allowing transactions to take place securely without anyone knowing either party’s real phone number. This feature works great for business models like ridesharing, where parties must communicate with each other but need to maintain a strict level of privacy.

This is a privacy and security-minded communications platform. Beyond masked calling, Twilio also has features for sending a verified caller label to the phone of anyone you’re calling, plus it actively combats caller ID spoofing. 

Twilio also includes its omnichannel Contact Center platform on select plans. This cloud-based feature is incredibly agile, allowing teams to personalize their call flows down to the tiniest details with routing rules, integrations, and call channels, making for efficient fielding of customer questions and issues.

Teams with high call volumes can use queue callback to let customers decide whether they’d like to wait in line or instead get a callback when a representative is available. Busy medical offices, for example, might activate this feature for patients to leave their name and number for a return call.

Training call representatives is also made easy through Aircall’s call monitoring and call whispering features. The latter lets a trainer guide the representative in real-time to ensure they handle calls properly.

Webex logo

Webex provides a straightforward business phone system with holding, call forwarding, and a personalized phone menu with extensions on all plans. Its mobile app is wonderfully convenient, allowing you to take calls, participate in meetings, and text from anywhere.

One perk for specific businesses and teams, like tech support teams or online healthcare companies, is the call-to-video feature. With the click of a button, a representative can transfer a regular phone call to a video call. Video calls come with recordings and transcriptions, too.

A massive array of integrations can bolster your Webex system to create an ideal customer contact solution for your business, including Webex apps such as Virtual Office for Public Services, Peak Analytics, and InformaCast.

800.com logo

As absolutely the best way to get toll-free and vanity numbers, 800.com is a great solution for making your operation appear bigger than it may be. Its basic plan also includes 1,000 minutes per month to the United States and Canada, but higher tiers offer unlimited calling.

With nothing to download and an elementary setup, you can get your business phone system up and running in minutes. Plans include detailed call tracking and analytics to gain insight into call trends, keywords, sales, and more.

The downside is the lack of a mobile app, so you’ll need to make any changes to your settings from the 800.com web portal.

eVoice logo

eVoice is a good option for solopreneurs or small business owners who get decent call volumes but don’t want to spend the majority of their day answering calls. Plans come with one free local or toll-free number, but you can add vanity or international numbers to your account as needed.

This is one of the few providers that make it easy to gain a virtual number for a different country, just be aware it will cost a bit to add it to your eVoice plan. But it can be worth it, considering that add-on unlocks calling to hundreds of countries, some of which are accessible at better calling rates than you’ll see elsewhere.

Regardless of your setup and the amount of numbers you need, you get unlimited calling to the United States for $14/user/month. That also comes with useful features like an auto-attendant.

Google Voice

Google Voice logo

Like other Google products, Google Voice comes with a beginner-friendly setup and interface that virtually anyone can figure out from the start. Switch between desktop and mobile apps with ease or just control everything on the go from your smartphone.

Google Voice is among the most reliable platforms out there, too. Dropped calls are slim to none, preventing unwanted interference when communicating with customers.

We do want to note this may not be the best option for businesses that make international calls. Google Voice charges a calling rate per minute for calls outside the United States or Canada. And, as far as virtual numbers go, you can only secure phone numbers in the U.S. (no toll-free options, either).

Learn how Google Voice works for businesses in our review.

The Best Business Phone System for Call Centers

Call centers take high volumes of calls on any given day, so call management features are of the utmost importance.

Nextiva logo

Nextiva truly does the most when it comes to call management. The powerful system handles every customer contact in a single app, including calls, messages, videos, and emails.

Call agents can jot down notes about customers before escalating or transferring calls. They can also add tags to customer interactions to keep like situations grouped together.

Dialpad logo

Dialpad relies on artificial intelligence to make your contact center the best it can be. The AI can detect specific keywords or phrases spoken on calls to alert a supervisor when they occur. It can also detect negativity during a call to let someone like a call center manager know that it might be time to intervene.

Supervisors or trainers can also participate in live voice coaching for agents in training to speak to them while they’re on a call. Or, send real-time messages to coach them without interrupting.

Dialpad offers encryption using TLS and is compliant with HIPAA, GDPR, and SOC2 Type II for added layers of security and privacy for your business and customers.

Vonage logo

Vonage includes several call management features most contact centers need, like call routing, call waiting, and optional continuous or on-demand call recording.

However, it also has perks that similar business phone systems don’t offer, like call screening with routing options, up to three devices on one extension, and an AI virtual assistant to help engage and drive customer conversations.

Vonage can also boost your team’s productivity by keeping your business tools connected through integrations. The system connects to popular tools like Zendesk, Microsoft Dynamics 365, and more.

What Matters When Reviewing Business Phone Systems

When combing through business phone systems, we found eight critical criteria for businesses to consider in determining their best fit. Our research team explored the way these criteria and the five use cases work together to ensure that we include only the most qualifying products in our guide. Below, we go into those eight criteria in greater detail.

Phone System Setup

No matter what you use your business phone system for, a straightforward setup and beginner-friendly usability are critical to successful integration with your company. Although an IT department can help set up the system for larger companies, each agent should be able to operate on the system with ease.

When It Matters Most:

  • Internal communication – Employees should be able to interact with each other quickly and reliably via a phone system with a clean and user-friendly interface.
  • External communication – You need a phone system that can be implemented quickly, to prevent any downtime in fielding or making calls to customers. 
  • Remote work – Setting up a system without equipment is key for remote workers who might prefer communicating using their computers or mobile devices.
  • Virtual phone numbers – Solopreneurs and small businesses can benefit from the simple setup that virtual phone number providers deliver.
  • Call centers – A platform built for call centers needs to easily be set up to deliver elements like detailed customer profiling and reporting, in-depth analytics, and training features.

Inbound and Outbound Call Tools

Businesses with high call volumes lean on business phone systems that can send customer calls to the right person and make it easy for agents to find customer information. 

When It Matters Most:

  • External communication – Phone systems with streamlined control panels and tools allow agents to look up and dial customers without sacrificing productivity.
  • Call centers – Agents who field dozens to hundreds of calls daily need features that simplify managing those calls.

Call Recording and Analytics

Businesses may record calls and monitor call analytics to ensure that customers’ needs are adequately met. For example, recordings can show supervisors when extra training might be necessary, while analytics could indicate areas of improvement with holding times, support escalations, and other factors.

When It Matters Most:

  • Call centers – Companies can reduce turnover rates and strengthen their customer support with the right recording and analytics tools.

UCaaS Features

UCaaS features bring together collaborative tools alongside an array of communication methods. From video calling and file sharing to texting and faxing, some businesses need a lot more than voice calling. 

When It Matters Most:

  • Remote work – A phone system with collaboration tools can assist remote workers in staying focused and connected, even when they’re miles apart.
  • Internal communication – From video conferencing to group messaging, a UCaaS-focused business phone system enhances a team’s communication ability without interfering with work.
  • External communication – UCaaS features like faxing, SMS/MMS messaging, and live chat keep agents in quick, convenient communication with clients and customers.

Desktop and Mobile Apps

Today’s desktop and mobile apps sync with one another so that users can switch between them seamlessly to take calls, answer text messages, and participate in video meetings.

When It Matters Most:

  • Virtual phone numbers – Remain accessible by phone anywhere with a virtual phone number that you can use from your current phone or a desktop app.
  • Remote work – Whether you run a remote business or you’re part of a remote team, having diverse options for accessing a phone system is a must.


Connecting your business phone system to the tools your team uses every day can streamline communications and productivity. For instance, some phone systems integrate with CRM software to make customer information available within seconds of a phone call.

When It Matters Most:

  • External communication – Spend less time switching between apps and more time focusing on customers and clients.
  • Call centers – Get access to customer information and their status within your pipeline with integrations with your CRM or marketing tools.

International Calling

Global businesses need to make and take international calls. However, if a business phone system plan doesn’t include international calls, overage charges can eat into a company’s communications budget fast. 

When It Matters Most:

  • Call centers – Large call centers often accept and make calls across the globe, so it’s necessary to have plenty of international calling minutes available. 
  • Virtual phone numbers – The option of having an international virtual phone number can ensure that you have a presence wherever you want more visibility.

Phone Security and Compliance

Many companies do a lot of business over the phone, meaning that sensitive information, like bank numbers and identifying data, travels over their phone lines. High-level end-to-end encryption and security can keep this information safe. Also, by law, your phone system may need to comply with specific regulations, like GDPR or HIPAA. 

When It Matters Most:

  • External communication – Encrypted data traveling to and from your company’s phone system can stay safe with a secure and compliant phone system.
  • Call centers – Keep customer information secure to provide an additional layer of trust in the company.
  • Remote work – Multiple device connections from various locations can lead to security vulnerabilities without the right phone system.
