DTMF 16000 Hz frequency

Asterisk Asterisk SIP
1

Hi Team,

I am using asterisk 13 and my provider is sending me an invite packet with updated SDP having the frequency of 16000 Hz
a=rtpmap:101 telephone-event/16000
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.

Asterisk does not support this currently, so there is no configuration that would allow it to work. It requires code changes.

Hi @jcolp
Thanks for your response.
Does asterisk provide support 16000Hz in higher versions or through pjsip?

No, noone has worked on adding such functionality.
