Network doesn't support video calls

I am using the newest beta version of Jami and Mate 20 Pro (EMUI 12)

Steps to reproduce:

Make a video call (Android -> Desktop)

You'll get this notification:

I think it's wrong because I've tried like 5 other messengers with video calls without any issues (same network)

Also I think sometimes video calls still work although this notification is shown

AND you can make an audio call and add video.

Is it related to Telecom API?

The error message is generated by the system / OS I think?

If this is related to telecom API.

changed the description

Looks like this: https://github.com/jitsi/jitsi-meet-sdk-samples/issues/62

Any update of this issue?

So it's system related: https://www.youtube.com/watch?v=tkYbKb-fbx4

But can you also create a patch that you don't need these system settings to be changed ?

same version: can't reproduce on Galaxy A53 5G (Android 13)

but I always reproduce on Mate 20 Pro (EMIU 12)

Are you using a WiFi network or mobile data? Seems not related to Jami but from the system.

Mobile data (LTE / 4G)

And for WiFI you don't have the issue?

Try with another LTE network. But I'm pretty sure it's your settings and not related to Jami (I don't even see this string anyway)

This string is a system string NOT a string of Jami.

But every other messaging apps don't show this issue if I make video calls. (And I think previous versions of Jami (like all from 2022) didn't show this error message)

And only Mate 20 Pro shows this error - Galaxy A53 5G for example never showed this error message.

Anyway - I'll try.

This doesn't change the fact that it's a system settings or network settings. The video is probably correctly detected on Jami and not on your other apps

Just tried out: It does not matter if I use mobile data (and a "real" SIM) or only WiFi (hotspot of the desktop pc).

Same issue

I have no clue. Every single similar issues I see is related to device cache or device network. Never from the app. Tbh I don't think we can do anything on our side for this.

Do you still envounter this issue ?

Can reproduce on Huawei Nova 5 Pro, but I can accept in video on the desktop device.

Just tried again - Same issue using Huawei Mate 20 Pro (EMUI 12.0.0.142 which is Android 11) - I get this error message but video calls work.

Other Huawei phone - Huawei Y9 (2019) with EMUI 9.1.0 (Android 9) - has the same issue - but video calls also work - so it's just a wrong error message of the OS ?

But no other messenger app has ever showed this issue - just Jami

@El4 I think Signal maintains a blocklist and disables Android Telecom Framework integration on specific devices.

Thanks for your answer. What happens if you disable the Android Telecom Framework integration? Is it related to Android Connection Service API ? Should voip call recording be still possible https://nllapps.com/apps/cb/voip-call-recording.htm ?
