RingCentral: Best Overall VoIP App for Multidevice Support
*Prices are based on one to 20 users. Discounts of up to 33% are available for users who opt for annual billing.
RingCentral is one of our recommended providers offering the best business phone system and the best overall VoIP app for users and accounts using different devices to access the platform. RingCentral’s desktop and mobile applications are seamless and full-featured. Coupled with the call flip feature, users transfer ongoing calls between linked devices with one click, offering mobility.
RingCentral’s app is straightforward, intuitive, and carries full platform functionality on its applications. However, for those who want simple calling features, it might take some getting used to. If this is the case, Google Voice is a simple application with straightforward controls enhanced by its Google Workspace integrations. Google Voice is available only to active Google Workspace users, and plan options include a free personal plan or paid subscription packages.
- Built-in customizability: Organize your display tabs and personalize your RingCentral app interface in the most helpful way. For example, your team members can select up to five tabs with calendars, tasks, videos, or other functions. This makes the app experience very convenient for each user.
- Call flip: Seamlessly transfer between softphone, mobile phone, and desk phone devices during ongoing calls. The call is placed on hold during the flip until the transfer is complete. This is particularly useful when you wish to continue a call on a different phone number or will be mobile mid-conversation.
- Extended voicemail options: There are multiple ways to check your voicemail using the RingCentral app. Users can listen to audio recordings, use voicemail-to-text (which allows you to read through your inbox), or read using voicemail-to-email (which compiles everything into your inbox).

Nextiva: Best VoIP App for Android Users
*Monthly pricing is based on one to four users. Save up to 27% with annual billing.
Nextiva came out on top of the list of VoIP apps for Android devices with its intuitive interface and features like MP3, WAV, and M4A file support when texting colleagues and customers on Android devices. Users easily place calls by tapping the dialer, locating a contact and placing the call, or clicking on the call or video icon and selecting contacts. Nextiva’s app allows you to transfer calls, add contacts, and screen share during meetings—all from your mobile device.
However, Nextiva users will find it has limited third-party integrations compared to other providers like RingCentral, which integrates with over 300 applications. Unfortunately, some important integrations are locked behind more expensive tiers. RingCentral is the mobile VoIP app with the most integrations and a robust API (application programming interface).
- Call pop: Call pop provides your agents detailed information about each caller. Your agents will see basic information, including the number used, the name of the caller, the priority level, and the details of their last interaction.
- Mobile screen share: Share any of your mobile tabs when you’re on a call. Android users will be able to screen share even if they’re using Android’s mobile split-screen feature.

Vonage: Best VoIP App for iPhone Users
*Pricing is based on one user. Vonage has a one-year minimum contract with cancellation subject to early termination fees.
Vonage offers the best VoIP app for iPhone users because it recently upgraded its features allowing users to make and receive home phone calls on up to two iPhones over the internet. Make calls wherever you are using your Vonage internet calling plan that comes with unlimited international calling to 60-plus countries. It lets you keep your mobile number private with its Caller ID feature that will show your Vonage number.
While Vonage offers great call features for those who want customizable call management plans, Vonage lacks key video conferencing features, such as virtual backgrounds, and only accommodates a maximum of 100 participants. If your business needs robust virtual meeting capabilities, 8×8 offers high-definition video and audio conferencing for up to 500 participants.
- Call block: This feature allows users to pre-determine calls and phone numbers that are blocked from making both inbound and outbound calls for extensions, including fax. Incoming calls from a blocked number will hear a fast busy, while outgoing calls to a blocked number will hear, “I’m sorry, Calls to this number have been blocked by your Administrator.”
- Vonage boomerang: Move all your calls from specific numbers to your Vonage number. Vonage automatically connects calls from your boomerang contact with all phone charges applied to your Vonage account.
- Receptionist console: The console views all call activity and uses call control tools, such as call park, call transfer, and call queue. Handle up to 50 concurrent calls and play a custom greeting or music to incoming callers.

Phone.com: Best for Softphone Users
*Save 20% with annual billing
Phone.com’s feature-rich VoIP phone app, Communicator, is excellent for businesses that predominantly use desktops for software-based dialing. Its softphone application supports both voice and video calling with customizable call management settings. It’s important to note that Communicator’s Mac desktop version has a few more on-screen features, while on Windows, you can access all available features under the “More Call options” drop-down menu.
Beyond these features, Phone.com doesn’t offer team messaging. If you need team chat for internal coordination, try Vonage, which offers unlimited team messaging. Stay constantly connected with colleagues through team messaging available via the Vonage Business Communications desktop and VoIP phone apps.

Grasshopper: Best for Teams With Basic Call Management Needs
*Grasshopper offers flat-rate pricing, not per user pricing; save 10% with annual billing
Grasshopper is the best voice-over-IP app for small businesses needing simple and easy-to-use virtual phone and call management systems. Its services, like calls, text messaging, custom greetings, extensions, and inbound fax, are all available with every plan. Make and receive calls and text messages anywhere and anytime with Grasshopper’s apps for desktop and mobile. Grasshopper offers 24/7 support access via phone, email, social media, and chat.
Unfortunately, Grasshopper allows international calling but lacks international numbers, which Phone.com’s offers. If you’re expanding and entering new global markets, this alternative would be a better fit for you. International numbers are available for all Phone.com plans starting at $4.99 per month for select countries. If you want more options, check out our list of the best services for VoIP international calls.
- Unlimited extensions: Grasshopper’s monthly flat rate allows for shared minutes and pooled messages, which is ideal for budget-conscious startups. Unlimited extensions mean your entire sales team shares a single phone number, with each agent assigned a specific extension allowing you to save on account fees.
- Instant response: Instant response reduces the risk of losing potential customers. When you cannot answer an incoming call, Grasshopper automatically sends an SMS message advising that you are unavailable, effectively informing your customer they’ve reached the correct number and you’ll get back to them.
- Voicemail: Voicemail is a feature included in all Grasshopper plans that allow your callers to leave you a message. Set up your voicemail so callers can leave you messages. Receive your recorded messages via MP3 recordings.

*Users subscribed to the X2 and X4 plans will save up to 23% with annual billing.
8×8 is our overall best VoIP calling app for international calls, with its comprehensive offering of unmetered calling in up to 48 countries. 8×8 offers a clear and reliable internet connection for businesses that make regular international calls and establishes a reputable virtual presence in regions where you have customers but no physical office.
While 8×8 offers comprehensive features, solopreneurs and freelancers often don’t need as many advanced features. Google Voice is an excellent option for professionals that use Google Workspace and need a virtual phone number and call management system. For those with low call volumes, avail of its free plan and upgrade as you scale. Unlike 8×8, Google Voice doesn’t provide international numbers and charges per-minute rates for calling outside the U.S.

Google Voice: Best for Google Workspace Users
*Requires active Google Workspace accounts to avail of Google Voice
Google Workspace users needing a virtual phone number for calls, texts, and voicemail can use Google Voice to make domestic and international calls from browsers and mobile devices. For users in the U.S., you can choose your number. This easy-to-use, free VoIP app is a simple add-on to active Google Workspace accounts.
At present, Google Voice does not support toll-free and vanity numbers. Phone.com, on the other hand, offers local, toll-free, vanity, and international phone numbers. Using different business numbers is a great way to make yourself more accessible to your customers and, in turn, boost sales and lead conversions.
