After upgrading from 188.8.131.52 to 184.108.40.206 there was no audio in telephone calls. The ringing was ok and a connection was established, but the telephone partners could not hear the other one. Restarts did not help.
By chance I stopped WLAN and restablished it. Afterwards the audio in telephone calls was working.
Does someone know what is going on there?
Is this a bug?
Best regards, Uwe.
