Issue with SDP - Call hangs up right after SIP 200 OK
Hello People, Ive been investigating an issue with SDP when sending a call to a Panasonic KX-TGP600 Phone, the call end as soon as the Panasonic send its SIP OK I could not see what is wrong with the SDP and why I get "INVITE: error parsing SDP answer in 200 OK" resulting in "988 Incomplete offer/answer" I also find it weird that there is no output for this error when Sofia debug is not enabled. It took me a while before I thought of trying to enable more debugging. There is also the "not found by name */1.1.217.127:1029" Part which I am not sure is related/relevant in this. -- Here is the console log portion that I thought was relevant: 2020-07-17 15:44:33.495660 [DEBUG] sofia.c:7325 Channel sofia/private/+15145557030@2.2.127.218 <mailto:sofia/private/+15145557030@2.2.127.218> entering state [early][180] nua.c:366 nua_handle_magic() nua: nua_handle_magic: entering 2020-07-17 15:44:33.495660 [NOTICE] switch_ivr_originate.c:556 Ring Ready sofia/private/+15145557030@2.2.127.218 <mailto:sofia/private/+15145557030@2.2.127.218> !

Hi, Your call is rejected by the sofia stack without even reaching freeswitch core as the 200 OK is incomplete. You have the following line:
m=video 0 RTP/AVP 34 0 16 178 64 0 16 178 0 0
But there is not rtpmap for codec 178. It is dynamic payload type so the rtpmap is required. Even the PT 64 is invalid as currently unassigned (https://www.iana.org/assignments/rtp-parameters/rtp-parameters.xhtml#rtp-par...) Best Regards, -- Valli A.

I could not see what is wrong with the SDP and why I get "INVITE: error parsing SDP answer in 200 OK" resulting in "988 Incomplete offer/answer"
I also find it weird that there is no output for this error when Sofia debug is not enabled. It took me a while before I thought of trying to enable more debugging.
There is also the "not found by name */1.1.217.127:1029" Part which I am not sure is related/relevant in this.
