Switch from mobile data to wifi:
Same, no sound or connexion issue.
If I restart call to the same room or another, I can't have connexion if I don't use the first networking protocol.
So, if I start call in wifi, I only make another calls in wifi for some time
If i start in 4g, I only can make with 4g...
