Connectivity issues

similar to #999 (but a new issue)

Android 20220906-01 (all devices)

turn enabled, both devices use the same WLAN (no internet access; calls always sameuseraccount (Mate 20 Pro; EMUI 12) → sameuseraccount (Tablet Android 8.1 Oreo) )

Android 11 (smartphone) - Android 8.1 Oreo Tablet

Steps to reproduce: Open Jami on the Android tablet and keep Jami running (never exit Jami)

Now just the Android phone:

Open Jami Immediately make a call (smartphone - tablet) maybe even BEFORE you can view the green dot Jami will show the making call symbol and

option 1: after some time the Android tablet user will get the call but is not able to answer (If the Android tablet user taps "Answer in audio/video" Jami won't respond. Only after many seconds the call suddenly is answered?

If I disable turn (both devices) I can immediately answer the call?

Option 2; the first call fails after some time (but no messages are displayed like "Connecting"etc; you make immediately a second call

It takes over 10(?) seconds until the Android tablet user receives the call

You'll receive the call (Androd tablet) but still can't tap "Answer in audio/video" (suddenly the call is auto-answered?)

Option 3: the second call will also fail but immedietaely
