Hi All, We have a SipXecs 4.4.0- 2011-05-10EDT22:48:21. Incoming calls from one particular operator on a SIP trunk fail. Further analyses has shown that the call is ended from the operators side (Tele2), after the 200 OK on the INVITE is sent from the SIPX In the 200 OK there is in the SDP a line with with:
m=image 0 UDPTL 19 which seems to cause the problem. As far as my knowledge stretches, this is a proper and allowed way to tell that (T.38?) is not supported on the call, port =0 after all.... Just to keep thing down to earth: is there a way to make SipXecs NOT send this line? In fact the operator in question should correct its behavior, but that may take a long time..... I have attached the pcap. Kind Regards, Peter van der Salm
