Best Softphones for iPhone & iPad in 2026
A practical roundup of the most reliable SIP softphone apps for iOS, with notes on call quality, push notifications, and battery impact.
By HelloPBX Team · May 12, 2026
A softphone turns your iPhone or iPad into a fully featured business extension. The right app means clear audio, reliable incoming calls even when the screen is locked, and a battery that survives the workday. Here are the apps we recommend for HelloPBX SIP accounts on iOS.
Our top picks for iOS
- Zoiper — polished interface, dependable push notifications, and excellent codec support (including OPUS and G.729).
- Linphone — open source, free, and great for testing; supports SIP over TLS and SRTP encryption.
- Bria Mobile (Acrobits) — premium app aimed at business users with robust background calling and CallKit integration.
- Acrobits Groundwire — power-user favorite with the best-in-class push and presence support on iOS.
What to look for
On iOS, the single most important feature is reliable push notifications. Apple aggressively suspends background apps, so a softphone must use Apple Push Notification service (APNs) to wake up for incoming calls. Apps with native CallKit support also display calls using the native iPhone call screen.
Enable push notifications and OPUS codec in your softphone for the best balance of call quality and battery life on cellular and Wi-Fi.
Recommended settings
- Transport: UDP on Wi-Fi, or TLS for encrypted signaling on untrusted networks.
- Codec priority: OPUS, then G.711 (PCMU/PCMA), then G.729 for low bandwidth.
- Enable push notifications so calls ring with the app closed.
- Set SIP host to dial.hellopbx.net and port 5060 (UDP).
