Mobile App
Testing.
A voice app that misses a push-woken call or dies in the background is a one-star review and a churned user, and the bug never shows up in an emulator. Test the real app on real Android and iOS devices in the Sipfront device farm, across WebRTC and SIP stacks like pjsip, including the push, background and power-save paths manual testing skips.

The failures that never reproduce on your desk.
Mobile voice apps are notoriously fragile. The hardest bugs live in the transitions a human tester rarely reaches by hand, and an emulator never reproduces faithfully.
Push-woken incoming calls
On mobile, an incoming call depends on a push notification arriving and waking the app. If FCM, APNs or PushKit is late or dropped, the phone never rings. We test it for real.
Power-saving & background
Doze, App Standby and iOS background suspension quietly kill sockets and miss calls. These are the states where mobile voice silently fails.
The call state machine
Foreground, background, killed and relaunched. Registration loss and re-registration. Network handover from Wi-Fi to LTE mid-call. The fragile paths real users hit daily.
WebRTC and SIP stacks
Native apps on WebRTC or on SIP stacks such as pjsip, validated with the same engine that drives Sipfront browser and SIP testing.
Real devices
Real radios, real OS power management, real audio routing. Emulators hide exactly the bugs that hit production.
Real audio and signalling
MOS, jitter, loss and the full SIP/WebRTC trace measured on the device, so a failure points at the cause, not just “the call dropped”.
From an app build to a pass/fail in the device farm.
Anyone shipping voice inside a mobile app.
If your customers talk through an app on their phone, the SIP trunk and the web client being healthy is not enough. This validates the part of the stack your user actually taps.
Mobile softphone vendors
Native iOS and Android softphones on WebRTC or pjsip. Prove the call connects, rings on push and survives backgrounding before the store release.
CCaaS & UCaaS with mobile apps
Agent and customer apps. Regression every release across OS versions and devices, not just the one phone on the tester’s desk.
Voice AI in apps
In-app calling to a voicebot. Validate that the call wakes, connects and carries clean audio on real handsets.
Teams chasing field-only bugs
Reproduce the “works on my phone” failures, by OS version, device model and power state, on demand.
Mobile App Testing is included from Carrier up.
Lens unlocks on the Carrier tier and above. Same engine, same dashboard, same evidence format as the rest of the platform.
