Incompatible SDP issue with telnyx sip points
ARMAN SINGH BALIYA
Hello There,
I'm trying to implement JSSIP with Telnyx SIP endpoint. in which endpoint are registered successfully, But outgoing calls getting cut just after one ring and in case of an incoming call, event of incoming is shown in the dev console but calls not working.
In case of an outgoing call I'm getting error code 488 and Error was, cause: "Incompatible SDP"
you can check below error object that is actual hangup cause of the call.
I talk with Telnyx support and they ask me to change the audio codec setting (It is an issue with the media attributes) with call. can you guys help me how can I change media attributes?. Last reply from Telnyx support is (The only thing I can say is to try to make it so the codec used is a=rtpmap:0 PCMU/8000)
