Best VoIP Softphone for iPhone Users

It can be difficult to choose the best softphone for iPhone users, especially with the wide variety of softphones available today. After doing some research, we found there are a number of options on the market that can fit many of your business needs. In the past, we've noted that the VoIP softphone offered in the AVOXI Genius platform is our top web-phone for desktop performance, but what about for mobile-users? To help make your decision a little easier, we downloaded a variety of apps, tested them and compiled a list of the best iOS SIP client applications.

Best SIP Client for iPhone

Bria 5

The Bria 5 is a next generation softphone that allows you to manage your communication needs efficiently, no matter where you are.  It allows you to make VoIP and video calls over IP, see when your contacts are available, send instant messages, and easily transfer files.

Bria's 5 release offers new features, such as a multiple license key capability that allows retail users to further enhance their communication software with add-ins and services like screen sharing and an integration for Outlook.

The Bria iPhone Edition, a SIP-based phone designed with the needs of iPhone or iPod touch users in mind, makes and receives calls using a Wi-Fi or data network connection.  Drawing on your existing iPhone or iPod contact list, you can manage communication through the Bria iPhone Edition's user-friendly interface.  Additional features include the capability to merge and split calls, complete attended and unattended transfers, and more.

Bria's iPhone Edition also includes features designed specifically for business and enterprise users, like audio encryption and secure call signaling.

The ZoiPer VoIP softphone is great for handling contacts and integrates well with mail clients such as Outlook, Thunderbird and Lotus Organizer.  Its multi-tabbed interface allows you to view all call logs and effortlessly change statuses to away or be right back.  By clicking the Contacts tab, you can manually add contacts from another source, or find contacts that are already available.

Pros

  • Video calls are effective
  • Manages all contacts well
  • Integrates well with various mail clients
  • Customize to match your brand

Cons

  • Some reviews state the new app version crashes on opening.
  • We received an error when configuring setup: 63, network unavailable. This error means that the non-ZoiPer service contact you are trying to reach is offline, or they are using an unsupported PBX server.

Sessiontalk

Sessiontalk offers a free to download iPhone VoIP client, with a good feature set included in their product. While they do not offer a lot on their website, their app in the App Store carries decent ratings. One thing they note on their website is their app won't drain your battery like some SIP apps tend to do, and will send you a push notification when someone is calling in and your application is closed. Some of their features include:

  • CallKit Support
  • Push notifications
  • Call recording
  • Video calls
  • SMS messaging
  • Call conferencing
