Really destroying SIP dialog ‘42e633c83044ca1675913e2c01e7c81e@52.232.129.229:5061’ Method: OPTIONS

The SIP provider ask if Asterisk could be configured to reply to option polling by way of a different SIP proxy address over UDP. While still maintaining TLS SIP signaling and Voice.

That log shows the provider responding to polls from Asterisk. It doesn’t show any being received from the provider.

Is this a continuation of a previous thread? If so please continue in the original thread, but note that I was a bit confused at the time when you said that Asterisk was responding after I explained your log was showing the provider responding, but I assumed you had found a example of a provider initiated OPTIONS in part of the log you hadn’t copied to the forum.

Hi David, this is a continuation of my previous thread. I will continue from the original thread.
