I am using asterisk 13 and my provider is sending me an invite packet with updated SDP having the frequency of 16000 Hz
the call is getting connected but the provider is unable to identify the dtmf inputs that being pressed.
In logs i can see the following error :
Processing media-level (audio) SDP a=rtpmap:101 telephone-event/16000… UNSUPPORTED OR FAILED.
Can you please help me in the same that whether i need to configure something at my asterisk end to handle this updated frequency.
