ERR has no write codec. [INCOMPATIBLE_DESTINATION]
Hi I wonder if anybody can help. We are getting an error creeping in on a production system. It is happening randomly which of course makes it difficult to track down. A call to a SIP registered endpoint (VoIP handset) randomly fails, it rings, then when it is answered the call fails. It could be to any of the end points on our system, it doesn't happen every call, in fact it only happens on prepositionally very few calls. If we restart the Freeswitch service the frequency of calls effected reduces to nothing and then builds up again.

Hi David, Have u checked your codecs in FS and end points? as we can see, you have some mismatch codec or transcoding problem.

Hi, Can you try disabling the comfort noise generation? You can do it by setting the profile param suppress-cng or the channel variable suppress_cng to true. It should remove the "a=rtpmap:13 CN/8000" line from your local sdp. Best Regards, -- Vallimamod Abdullah SIP Solutions vma@sip.solutions linkedin.com/in/vallimamod .
