Hello,
my Asterisk 22.0.0 is up and running.
Connected with Sipgate (German SIP provider).
Normal incomming and outgoing calls are without any problems, the quality is G.711, but I acept G.722 too.
In the folling szenario sometimes the audio is with interferences - 50/50 mixed like wrong codec.
It sounds like mixed alaw with ylaw or 50% is set to high.
Caller External is ralling the Asterisk via Sipgate.
User a is Answering and speaking - clear without any interferences
User a (on Snom D385) is pressing the ATXfer button on Snom (ATXFER ist starting)
External is heraing dubidubidu - MOH is playing.
User a is dialing User b (on Snom D385 too or MicroSIP on PC)
User a is speaking with User b “there is external in the line, I will stop an you can speak”
User a is prssing the transfer Button on D385,
User a is ended
External stopped MOH and connect to User b.
User b can speak with External with massive interferences
External can speak with User b with massive interfrerences
User b hang up the line and dials out - external is ringing and the connection is without any problems.
I suspect that the MOH pulls the external participant to some COdec and does not come back after connecting to b.
