Having new VoIP challenge today.
How to make softphone work in background – Zoiper 5 specifically, even when device rebooted, or app never started (like after OS reboot).
Interested in iOS or Android.
It seems that an extension I did test today, Asterisk transport was UDP (they recommend it to be TCP). It caused app to work only when app is on the screen, but when minimized no joy, it was iOS.
Is it possible to achieve near 100% app readiness in the WLAN with their Push Proxy paid service? Or, share how you work around this!
