How We Evaluated VoIP Apps for iPhone
Most VoIP business phone systems offer a mobile app for iPhone as a standard feature with their service plans. However, to be considered the best, the app should be easy to use and integrate with iPhone features like contacts and email. They should also include features helpful to workers on the go, like conference calling, instant messaging, and voicemail. VoIP apps for iPhone should also be affordable and backed by reliable customer support.
Therefore, we evaluated the best VoIP apps for iPhone based on:
- Price: Each provider’s pricing tiers and packages were compared as a business phone system overall in addition to the cost of the app.
- Ease of Use: We evaluated how easy each VoIP app was to set up and use.
- Integration with Apple Products: We checked how well each app integrated with the iPhones native features like Contacts and devices like Apple Watch.
- Call Features: Each app considered had to support core calling features like the ability to make and receive phone calls using the business number as well as more advanced functionality like call hold or transfer.
- International Calling: We looked at each service’s ability to make calls outside the United States.
- Integrations: A VoIP app should work with the business phone system, however, we also examined each app’s ability to connect data with other business applications.
- Additional Features: We evaluated the variety of uncommon or bonus features included with each VoIP app.
- Customer Support: We assessed each provider’s online and live customer support.
Based on our research, we recommend Ooma as the best overall VoIP app for its affordability and combination of features like conference calling and an auto attendant. In addition to it being a business phone system, it also offers a great mobile app as part of all of its service plans along with exceptional customer support, making it particularly well-suited for growing businesses.
Best Overall VoIP iPhone App for Small Businesses: Ooma
Ooma is a VoIP business phone system for $19.95/user per month that includes an iPhone app. The mobile app, which supports basic call management functionality like voicemail and less common E911 emergency service also offers faxing and a conference bridge that supports up to 10 participants. Ooma is right for companies wanting an affordable VoIP system with an iPhone app that has the best combination of features.
Ooma’s pricing is $19.95/user per month, and a one-time hardware charge of $129.97 for a base station and two wireless Linx devices. Accounts include one local or toll-free number, a virtual fax number, and a conference line number. Additional local or toll-free numbers are available for $9.95 each per month.
Ooma’s features include unlimited calling to the U.S., Canada, Mexico, and Puerto Rico, auto attendant, a conference bridge, voicemail, and call management tools. It also offers auto-forward during device outages and E911 emergency calling service where supported.
Additional Ooma features include:
Ooma’s mobile app is available for all customers. Features include hold music, voicemail access, outbound Caller ID with the user’s Ooma phone number, call transfer, WiFi calling, and a conference bridge that supports up to 10 people. Customers can also access Ooma’s auto attendant that routes calls by name or extension number to a virtual extension, physical extension, ring group, or voicemail box through the app.
Ooma’s call management tools include voicemail, call transfer, park, and call forwarding to mobile devices. Ooma also offers “ring group,” a feature that allows multiple phones to ring simultaneously when one number or extension is dialed. Each user extension includes a voicemail box with a personalized greeting and an individual portal to check call logs, listen to voicemail, and send faxes.
Ooma’s auto attendant routes calls by name or extension number to a virtual extension, physical extension, ring group, or voicemail box. It also includes greeting configuration options for business hours and after-hours calls and tools to allow users to create personalized company greetings and announcements. RingCentral’s auto attendant, available with mid-level plans and higher, offers similar greeting and routing features but at a greater cost.
What Ooma Is Missing
Ooma is missing a video conferencing feature as offered by competitors like Vonage. Ooma is also the only provider on our list with upfront costs associated with the hardware equipment purchase necessary to set up the service for the first time. Businesses that consider that a drawback should try Nextiva or Vonage instead.
What Users Think About Ooma
Our readers give Ooma high marks with a 4- out of 5-star rating. Customers say the user interface is intuitive and customer service is responsive. However, some users were disappointed to discover it’s only possible to port phone numbers, not extension numbers. For more user reviews, visit our Ooma User Review Page.
Where to Find Ooma
Businesses wanting a robust set of business phone and iPhone app features at an all-inclusive monthly price should take a look at Ooma. The company offers a 30-day money back guarantee and a free 30-day trial. Check out Ooma’s website for details.

RingCentral is a VoIP phone service with an iPhone app that, in addition to call management features and supporting calls over Wi-Fi, includes Apple Watch integration. Plans start at $29.99/user per month and also comes with unlimited domestic calling and a multi-level auto attendant. RingCentral is right for agents that want a mobile VoIP app that supports notifications and calling through Apple Watch.
RingCentral’s prices for up to 10 users range from $29.99 to $39.99 per month. Unlimited user plans range from $34.99 to $44.99 per month. All plans have an annual contract option for a discount on the cost per user. Customers who pay by the month can cancel any time without penalty.
RingCentral Tiered Features
|Unlimited Audio and Video Meetings|

|Integrations with Microsoft, Google, Box, and Okta|
|iPhone App with Apple Watch Integration|
|Call Flip, Transfer, & Park|
|Standard Call Recording|
|Call Log Reports|
|Automatic Call Recording|
RingCentral Essentials includes 100 toll-free minutes, unlimited audio and video meetings for groups of up to four people, and unlimited calling. The iPhone app offers call flip, transfer, and park as well as the ability to take calls over Wi-Fi without using your carrier minutes. The Essentials tier, which starts at $29.99/user per month, is right for small teams and businesses wanting no-frills VoIP phone service that includes a mobile app for iPhones.
However, this tier doesn’t offer a large bucket of toll-free minutes or the multi-level auto-attendant features found in the higher level packages. It’s also missing support for conference calling that’s included with Ooma. However, not all solutions offer basic packages with audio and video conferencing which is a nice feature of this plan.
RingCentral Standard includes 1,000 toll-free minutes and adds a multi-level auto-attendant with several call routing features, including the ability to direct calls to multiple locations or external phone numbers. With pricing from $34.99/user per month, this tier also adds VoIP app support for faxing and call recording, making it right for teams that need to send and receive faxes while out of the office.
This plan doesn’t offer as many toll-free minutes as the higher-level package automatic or the call recording feature found at the next level. It also lacks an image sharing feature that’s included with Vonage’s iPhone app. However, this tier offers more toll-free minutes than other VoIP providers. RingCentral Standard is right for sales teams and call centers wanting a VoIP phone service with inbound call management tools.
RingCentral Premium is designed for businesses with larger teams or higher call volumes and includes 2,500 toll-free minutes as well as unlimited audio and video meetings for up to 100 people. In addition, this tier also adds automatic call recording and voicemail transcription-to-text with pricing from $44.99/user per month.
Overall, while RingCentral offers many of the same features as other VoIP phone service providers, its unlimited video meetings, generous toll-free minutes, and integrations with business apps work together to give small businesses more options to better serve customers. RingCentral Premium is a good solution for larger call centers and business wanting digital records of calls for quality assurance, training, and compliance purposes.
What RingCentral Is Missing
RingCentral’s service plans lack unlimited calling outside the U.S. and Canada. VoIP users with global contacts, clients, and customers would be better served by Jive, which offers international calling to 52 countries.
What Users Think About RingCentral
Our readers give RingCentral positive ratings with an average of 4- out of 5-stars. Customers say RingCentral has all the features that a small business needs. However, some users are disappointed with RingCentral’s customer service, reporting long phone hold times and email response times. To learn more, visit our RingCentral User Reviews page.
Where to Find RingCentral
Sales teams and business owners wanting a VoIP business phone service with a mobile app that integrates with Apple Watch should look at RingCentral. The company offers a free trial of its product and 30-day money back guarantee when you purchase an account. Visit RingCentral’s website for details.
Best VoIP iPhone App for Screen Sharing: Nextiva
Nextiva is a top VoIP business phone system with features like unlimited calling and conference calling from $19.95/user per month. Its mobile app for iPhone includes the less common feature of mobile screen sharing, making Nextiva best for people like service agents who need to be able to view files or troubleshoot client software issues over the phone while out in the field.
Nextiva offers three service plans. Pro starts at $20 per month for teams of more than 100, Pro Plus begins at $25 per month, and Enterprise starts at $30 per month. Pricing is per user, and prices increase for smaller teams. However, additional cost savings are available with long-term contracts and prepaid agreements.
Nextiva Tiered Features
|Professionally Recorded Greetings|
|Free Local & Toll-Free Number|
|iPhone App With Screen Share|
|Analytics & Reporting|
Nextiva’s Office Pro package includes unlimited domestic calling, free local and toll-free phone numbers, and an auto attendant. This tier also offers voicemail-to-email transcription and a cloud PBX to receive and route incoming calls. With pricing that starts at $20, Nextiva Office Pro is a good fit for small companies and teams wanting basic business VoIP phone service.
It’s important to note that the Pro package does not include a mobile VoIP app, or the conference bridge and call recording features found in upper levels. It’s also missing features that Vonage offers in its first-level package, like SMS and messaging. However, this plan is priced similarly to other tier-one packages on our list.
Office Pro Plus
Nextiva’s Office Pro Plus package adds a VoIP app for iPhone users that features screen sharing, instant messaging, call logs, and conference calling, with pricing that starts at $25/user per month. The Office Pro Plus plan is a good fit for business owners and teams who want to stay connected to each other and collaborate on screen while outside the office.
This package lacks the reporting, call recording and CRM features offered at Nextiva’s highest tier level. It’s also missing additional collaboration features like group conversations and image sharing, like Vonage offers. However, this plan’s pricing is on par with other mid-range service plans on our list.
Nextiva’s Office Enterprise business VoIP plan includes inbound and outbound call recording and three professionally recorded greetings. It also adds CRM features and tools for analytics and reporting with pricing that begins at $30/user per month. Office Enterprise is a good solution for business owners that want to capture call data for quality assurance and strategic planning.
On the whole, Nextiva offers most of the standard phone system features business should expect from a VoIP phone service provider, but Nextiva’s primary differentiator from other solutions is the high standard of customer support it delivers. New customers are assigned a single point of contact that remains in place from setup and training to ongoing support, and is a reason why it was named as our top pick in our comparison for business phone systems.
What Nextiva Is Missing
Nextiva delivers the best balance between features and price. However, this VoIP phone system is missing a few of the more advanced features that RingCentral offers, such as unlimited video meetings with screen sharing, integration with Microsoft, Google, Box, and Dropbox, or toll-free minutes.
What Users Think About Nextiva
Our readers give Nextiva positive ratings overall with an average of 4.5 out of 5 stars. Users say that Nextiva’s customer service representatives are helpful and professional. However, users also say the system can be difficult to install and use, and they complain of frequent downtimes. For more reviews, visit our Nextiva User Reviews page.
Where to Find Nextiva
Organizations wanting a business phone system with an iPhone app that features screen sharing for collaboration with co-workers should give Nextiva a try. The company offers a free demo of its product when you contact the sales team. Head to Nextiva’s website for details.

Vonage is a VoIP phone service provider with an iPhone app that features team collaboration tools like group conversation which can be accessed by either the mobile or desktop app, image sharing, and text messaging. Plans start at $19.99/user per month. Vonage is best for consultants and sales teams that use collaboration tools like group conversation to work with teammates while out of the office.
Vonage offers three packages. Mobile starts at $19.99 per month, Premium starts at $29.99 per month, and Advanced starts at $39.99 per month.

|Voicemail to Email Transcription|
|Music On Hold|
|On-Demand Call Recording|
Vonage Mobile includes unlimited calling, SMS messaging, voicemail, image sharing, and group conversation through the mobile and desktop apps for $19.99/user per month. This level also includes call management tools, call screening, and call continuity to prevent service interruption during a power or internet outage. Vonage Mobile is right for distributed and remote teams or businesses without a central office.
This tier doesn’t include CRM integration, video conferencing, and the multi-level auto-attendant offered at the next level. It also lacks a free local and toll-free phone number offered by Nextiva’s first-level price plan. However, a local phone number is available for an additional $9.99 per month and a toll-free number is available for an additional $39.99 per month.
Vonage Premium adds video conferencing, chat, and file sharing through Amazon Chime to desktop and mobile devices for up to 100 people for $29.99/user per month. This level also includes a multi-level auto-attendant and CRM integration for Salesforce, SugarCRM, Zoho, and more. Vonage Premium is best for companies wanting a VoIP phone system that communicates with their business apps and customer relationship tools.
This tier lacks the call recording and visual voicemail offered at the premium level. It’s also missing a conference bridge and online faxing offered standard by Nextiva. However, both features are available for an additional $14.99 per month, plus $0.03 per minute $14.99 per month, respectively.
Vonage Advanced adds visual voicemail and 15 hours per month of on-demand call recording allowing employees to decide when they want to record calls. It also includes call group to forward calls to multiple extensions simultaneously. At $39.99/user per month, Vonage Advanced is a good choice for business owners wanting assistance setting up new VoIP phone service.
Altogether, Vonage offers many of the same call management features as its competitors, whether standard or a la carte. However, the on-demand call recording feature sets this tier apart from other VoIP iPhone app providers by allowing users to record calls at will via the iPhone app when out of the office for later review and reference.
What Vonage Is Missing
Vonage lacks the ability to hand off calls to a desk phone or other device without first disconnecting the call. Business owners that want seamless call handoff to other devices should consider Nextiva or RingCentral instead.
What Users Think About Vonage
Our reader reviews are mixed with an average of 3 out of 5 stars. Some customers say Vonage’s call quality is better than other VoIP systems out there. However, others report that the system doesn’t scale well and technical problems arise the more users are added to the network. For more reviews, visit our Vonage User Reviews page.
Where to Find Vonage
Organizations and teams that want an iPhone VoIP app with collaboration tools like video meetings, image sharing, and group messaging should consider Vonage. The company offers a 14-day free trial to try before signing up for an account. Visit Vonage’s website for details.
Best VoIP iPhone App for Faxing: Grasshopper
Grasshopper is a virtual phone system that provides key business phone features right on your iPhone, including the ability to sign and send faxes, while not requiring you to purchase an additional set of desktop phones. Prices start at just $29 per month and is the best service for freelancers, consultants, or solopreneurs that need to be able to sign and send faxes while out of the office.
Grasshopper offers three competitively-priced service plans: Solo for $29 per month, Partner for $49 per month and Small Business for $89 per month. All plans offer all of Grasshopper’s virtual phone system features, such as auto-attendant, unlimited minutes, voicemail to email and extensions for forwarding.
Each plan includes phone numbers and extensions:
- Solo Plan: One number and three extensions for $29 per month
- Partner Plan: Three numbers and six extensions for $49 per month
- Small Business Plan: Five numbers and unlimited extensions for $89 per month
Grasshopper includes a number of features that give solopreneurs or remote employees the same tools that many traditional small business phone systems provide, such as call routing, voicemail, and fax. It also features a customizable auto-attendant, hold music, a dial-by-name directory, voicemail-to-email, and business texting.
Grasshopper’s features include the following:
Grasshopper’s iPhone app features text messaging, visual voicemail, and spam call detection. It also includes the ability to receive faxes to view online or in email as well as sign and send faxes and PDFs. RungCentral also includes virtual faxing but it’s only available with its middle-tier and premium plans which start at a more expensive $34.99/user per month
Grasshopper’s call management tools include call forwarding, call transfer, call block, and custom call control schedules for your business hours. Like Vonage, Grasshopper also offers call screening. This feature allows you to hear the caller’s name or number before deciding whether to take the call, which is helpful if you take personal and business calls on the same phone.
Grasshopper’s automated attendant answers inbound calls, then forward it to the employee or the department the customer or client is trying to reach. Similar to Nextiva’s auto-attendant, users can record personalized messages and announcements via Grasshopper’s desktop app to use with the system’s custom phone greeting feature that plays automatically when a customer calls.
What Grasshopper Is Missing
Grasshopper lacks advanced calling features that larger VoIP providers like Nextiva or Vonage offer, but this is reflected in Grasshopper’s lower cost. However, because Grasshopper is a virtual phone service, the most significant missing feature is the phone service itself. That means you’ll use your mobile phone plan’s minutes unless you’re connected to Wi-Fi when you’re making and receiving calls.
What Users Think About Grasshopper
Our readers give Grasshopper mixed reviews with an average of 3 out of 5 stars. Users say they love its pricing and reliability, and that the customer service team is helpful. Those unhappy with the service mostly had difficulties in managing and configuring the call forwarding service. For more reader reviews, visit our Grasshopper User Reviews page.

For instance, users can set up a rule that turns off the Do Not Disturb feature when they return to the office.
Jive offers a range of call management features, including call transfer and forwarding, call waiting, and caller ID. It also includes do not disturb, auto-reject, and automatic call queue distribution to minimize caller wait times. RingCentral also offers these call management tools along with features like call monitoring and call screening. However, some features, including caller ID with name, aren’t available in RingCentral’s entry-level service plan.
Jive’s auto-attendant greets callers with a brief customizable message and routes calls based on the caller’s keypad input. The auto-attendant also allows admins to create different routing rules for a variety of situations including when a business is closed or during modified working hours. RingCentral offers a multi-level auto-attendant with additional features like the ability to route calls outside of the company, but it’s only available with the mid-range tier and higher.
What Jive Is Missing
While Jive offers several help features for managing customer calls, such as wait time announcements, unlimited call queues, and queue call recording. However, it’s notably lacking customer relationship management tools to allow agents to make notes on calls or integration with existing CRM platforms. Businesses wanting a solution with CRM integration should check out Nextiva instead.
What Users Think About Jive
Our readers give Jive good reviews on average with a rating of 3- out of 5-stars.
