Hi All,

Actually while seeking the solution in internet I see some people having this problem with sofia library. I'm not sure that SIP reply in this case contains a valid SDP (I think that teminating endpoint is broken) but in my opinion if we have at least one valid media type in SDP (video, audio, image ...) call must be established. Can someone comment and/or help me with this issue.

Regards.

Hi all,

Dose someone have a problem that if there T.38 in coming from gateway FreeSwitch drops the call because of media error ? As I see from log only T.38 port is zero and SDP has also media port. Is it possible to configure FS to do not break a call but if media is OK.
