- It offers 300-plus third-party integrations.
Where It Falls Behind
- It has limited SMS credits per month.
- It can be pricier than most competitors.

RingCentral wins as the overall best iPhone VoIP app for business users needing access to various call features straight from their mobile devices. You get all the desk phone functionalities along with advanced call management capabilities, like multilevel auto-attendant, answering rules, and call flip.
As the industry-leading VoIP phone system, RingCentral is more than just a full-featured phone service. It works as a personal artificial intelligence (AI) assistant that generates real-time call notes, writes polished messages, and creates video meeting highlights. The AI noise cancellation reduces the background sounds on your calls and meetings, ensuring quality conversations.
On the downside, RingCentral’s extensive list of tools may be more than a startup or small team needs. If this is the case, Grasshopper, a straightforward VoIP iPhone app offering essential features, is a better option. It also supports unlimited users for a fixed monthly fee.
RingCentral Features

- Call-to-video: Switch a live call to an active video meeting or simply share your screen during a 1:1 call. This allows you to conveniently switch channels without interruptions.
- Call forwarding: Automatically forward calls to any office, home, or mobile number to ensure no phones go unanswered.
Dialpad: Best for Smart Voice Features
What We Liked
- It offers international SMS and phone numbers.
- It has a modern user interface.
- It offers local number support in 70-plus countries.

Dialpad leads the pack as the best iPhone VoIP app when it comes to artificial intelligence (AI) features, reducing manual and repetitive work in managing business calls. Built-in AI features transcribe conversations, capture recaps of every call, and send post-call summaries directly to your inbox.
AI features are also part of Dialpad’s video conferencing tool, allowing you to automatically take notes and determine action items during a meeting. This helps teams focus on more technical tasks and removes time-consuming activities like drafting meeting summaries. Dialpad also supports seamless device switching, so you can move phone calls from one device to another.
Note that Dialpad’s VoIP plans can only support up to 10 participants for video meetings. You might want to consider another iPhone VoIP app like RingCentral, which has up to 200 meeting capacities. It has the same AI features as Dialpad and has an optional large meeting add-on.
Dialpad Features

- Call flip: Seamlessly move between devices during an active call without disrupting the conversation flow. Move from the desktop app to your phone and vice versa without disconnecting the call.

- Toll-free number: Get a toll-free or 1-800 number and allow customers to reach you for free. All Dialpad plans come with toll-free phone number support. Additional toll-free numbers start at $15 per month.
Grasshopper: Best for Business Texting
What We Liked
- Solo Plus and Small Business packages support unlimited users for a fixed monthly cost.
- It offers a dedicated phone plan for solopreneurs.
- All plans have the same number of VoIP features.
Where It Falls Behind
- It doesn’t support chat and video.
- It has limited VoIP features.
- It lacks third-party integrations.
Grasshopper Monthly Pricing Save up to 20% with annual billing.
- True Solo: $18 for one user, one phone number, and one extension

- Small Business: $70 for four phone numbers and unlimited extensions

All plans include business texting, call forwarding, voicemail, custom greetings, incoming call control, and reporting.
Grasshopper is our best voice-over IP app for iPhone specifically for businesses that use text messaging as their primary communication channel. While most providers limit SMS credits per plan, Grasshopper supports unlimited texting, so you can send updates and quick replies to customers without worrying about overage fees.
To enable unlimited text messaging, you need to pay a one-time fee of $19 in compliance with The Campaign Registry (for US numbers only). Leverage business SMS using the instant response feature to send automated replies to missed calls from first-time callers. You can customize your messaging by adding pictures and website links.
Grasshopper lacks unified communication features like video calls and team chat. Collaborative teams may want to consider Nextiva, an all-in-one communication platform for video meetings, productivity, team messaging, and customer engagement.
Grasshopper Features

- Wi-Fi calling: Use the best connection available and make and receive calls on a Wi-Fi network, perfect for areas with poor cellular reception. Using Wi-Fi for outbound communications saves you minutes and cellular data.
- Simultaneous call handling: Limit missed calls by setting up multiple call forwarding numbers and answering all incoming calls, even during peak call times.
Nextiva: Best for Multichannel Client Interactions
What We Liked
- It offers generous SMS credits.
- It includes up to 12,500 toll-free minutes.
- It has an intuitive call flow builder.
Where It Falls Behind
- Its base plan lacks text messaging.

Nextiva is our best VoIP phone app for iPhone, thanks to its mobile-accessible customer engagement platform. This works for remote teams needing access to customer interaction channels like voice, video, email, and SMS. Its customer conversation suite brings all these channels into one place, providing a full view of customer communication history.
The NextivaONE app lets you instantly start meetings, make calls, and send messages to your customers from anywhere. Customer engagement tools sit alongside team collaboration tools, so you can coordinate with external departments when handling an inquiry.
Despite Nextiva’s impressive customer-centric offerings, its full-featured conversation suite can be overwhelming for solopreneurs or small teams looking for a less complex solution. If this is what you need, you’re better off with a customizable VoIP phone app for iPhone, like Vonage that lets you choose only the features you want for your business.
Nextiva Features

- Team chat: Chat with colleagues instantly with Nextiva’s secure chat. Communicate in real-time, screen share, see your message history, and hop into video calls with one click.
- DND: Activating this feature automatically ignores all incoming calls. Callers will either hear a busy signal or be rerouted to your voicemail.
- Auto-attendant: Callers will hear an instant automated greeting that allows them to choose the person, extension, or department they wish to reach. Calls are managed without the need for a physical receptionist.
GoTo Connect: Best for International Calling
What We Liked
- Its Phone System plan scales into a call center solution.
- It offers unlimited calls to 50-plus countries.
- It offers complete phone features.
Where It Falls Behind
- Its pricing is unpublished.
- Custom roles are exclusive to contact center users.
- It lacks cloud storage.
GoTo Connect Customized Pricing
- Phone System: 1,000 toll-free minutes, unlimited global calling, smart call routing, call queues, call handling, team chat, and video meetings
- Customer Engagement: Shared inbox, virtual assistant, surveys, SMS/MMS campaigns, and custom analytics dashboards
- Complete CX: Advanced call routing, skills management, agent monitoring, supervisor analytics, and queue callback
- Contact Center: Screen recording, quality management, auto dialer, and workforce management integrations
We pick GoTo Connect as the best app for VoIP calls on iPhone as it supports free unlimited calls to over 50 countries. This is suitable for companies wanting to expand overseas and connect with customers without setting up a physical office or paying for long-distance calls.
Another main highlight of GoTo Connect is its flexible voice plans, scaling from a basic phone system to a comprehensive contact center platform. This makes it easy for growing businesses to scale their communications infrastructure based on their call volume and requirements.
One major drawback of GoTo Connect is its lack of pricing transparency. While custom pricing is ideal for tailored communication needs, it may not work for small businesses wanting to get a clear view of their costs. In this case, choose a fully transparent provider like Vonage, a VoIP app for iPhone users seeking pricing flexibility.
GoTo Connect Features

- Custom auto-attendant: Add customized messages and greetings to your automated phone system. Record the message within the GoTo Connect plan and add it to the visual call flow editor to apply the changes.
- Call filtering: Route incoming calls based on the caller ID. For instance, you can direct VIP callers straight to a representative without passing through a virtual receptionist.
- Visual dial plan editor: A graphical interface maps out call flows using drag-and-drop elements. Set various call patterns for business hours, after-hours, and holiday hours.

MightyCall is the best VoIP app for iPhone users needing access to call center features right from their mobile devices. Generally, VoIP providers lock agent tools in higher service tiers or on a separate contact center plan, which can be costly. With MightyCall, all monthly plans include essential call center capabilities like agent workspace, CRM integrations, and call recording.
The MightyCall iOS app provides all the call management capabilities you need to manage calls when out of the office. Although setting up admin features requires the use of a web browser, you can still carry out most activities, like taking calls, changing your status, and syncing your CRM with the MightyCall app.
Apart from Salesforce and HubSpot, MightyCall lacks built-in integrations with many third-party tools. If you’re looking for a fully integrated VoIP app, check out RingCentral. This provider connects with over 300 apps and has complete collaboration capabilities like team chat and video conferencing.
MightyCall Features

- Caller ID Name (CNAM): Customize your outbound caller ID by adding your company name. When you make a call, your business name will appear on the recipient’s call screen instead of your number.
- Call duration limits: Set the maximum duration for incoming and outgoing calls. This ensures conversations remain within the specified time frame.
- Call intercept: Disconnect an agent from attending an ongoing call and allow a supervisor to barge in and take over the call. This can be used to assist agents when dealing with rude callers, so another user can handle the situation effectively.
Vonage: Best Customizable VoIP App
What We Liked
- It can integrate with Siri.
- You can purchase additional features based on your needs.
- All plans include 40-plus calling features.
Where It Falls Behind

Vonage is a flexible iPhone VoIP app that lets you modify the number of features and integrations you need for your business phone system. All plans come prebuilt with 43 standard voice features and 20-plus integrations, but you have the option to purchase additional tools and apps as you like.
There are 18 paid add-ons to choose from, such as virtual extension, virtual assistant, online fax, and on-demand call recording. Add-on fees range from $4.99 to $49.99 per month. The Business Inbox is a premium Vonage feature for consolidating SMS, MMS, and Facebook chat messages in one place.
If you find that most of the features you need are paid add-ons, then a la carte pricing may not be your best pricing model. If you have a limited budget, consider Grasshopper. It has many essential business communication features that small businesses need and offers flat-fee pricing. Grasshopper’s True Solo plan starts at $18 per month.
Vonage Features

Talkroute: Best Beginner-friendly VoIP App

- You can pay as low as $5 monthly for every additional user.
- It has highly customizable call settings.
Where It Falls Behind
- It relies on Zapier for prebuilt integrations.

If the feature-rich offerings of other providers don’t work for you, then Talkroute makes the perfect alternative. Talkroute is an iPhone VoIP app emphasizing simplicity and user-friendliness, ideal for those new to cloud phone systems. Its iOS version has accessible call functions that make it easy to switch between different phone numbers and manage your business calls on the go.
Starting at just $19 monthly, this provider offers text messaging, unlimited calling, video meetings, and a wide range of basic call features. These include call routing, voicemail boxes, custom greetings, and virtual phone numbers. Despite lacking AI and automation features, Talkroute’s straightforward nature makes it a good fit for those who prefer a no-frills VoIP platform.
Note that Talkroute relies on a third-party solution called Zapier to integrate with other business software. This can lead to additional costs and training if you choose this route. If you want to connect your existing app stack to your VoIP software, we recommend fully integrated providers like RingCentral, Dialpad, and Vonage.
Talkroute Features
