Re: [reSIProcate-users] Why the UAS send 500 Server Interna error when received re-INVITE?
I'm using the Helper::
makeRespone and Dum:send to send the 415.
I just want to ignore this T.38 FAX offer, don't want hangup this call, if use InviteSession::reject with 488, the call will be closed.
Do you have any other better idea?
Thanks

Please examine/post the resip logs at DEBUG or STACK level - these are far more useful then just seeing the SIP messages only when trying to understand what's going on. What API did you use to send the 415? I suspect you didn't use InviteSession::reject - so DUM still thinks the last re-invite is in progress.
On a side note - you should be using 488 to reject the SDP offer, 415 is only used if you don't accept the Content-Type - in this case it's SDP, so you do accept it. See section 13.3.1.3 of RFC3261.

First the call is incomng and my phone anwered. After call established, the caller send a re-INVITE(update INVITE), this re-INVITE SDP is for T.38 FAX, my phone not suppot so responed "415 unsupported media type". Afte a while, the caller send a re-INVITE again with an audio offer, why resip rejected it by 500 Sever Internal error ? I have attached the log file in mail.
Thanks
