Mobile iOS with 2 SIM cards has issues during call via Talk

[AssiaAzzouzi]

Steps to reproduce

1. Keep 2 SIM cards activated
2. Participate in a call on Talk

Expected behaviour

Should hear and be heard by other participants in the call.

Actual behaviour

Not heard by some participants and heard by others.

If I leave the call and Talk app, disable one of the two SIM cards, open Talk app and join the call again, I can hear and be heard by all the participants.

Hey @AssiaAzzouzi,

thanks for opening the issue and providing the details, especially to the WebRTC bug. We are going to take a look later this week and try a few things.
