Hi, Samsung PBX's generate a wrong CANCEL:
- It contains To tag !!! - It contains "application/sdp" mirroring the SDP of the 183 received !!!
Really ugly. Actually those CANCEL's are being rejected by my kamailio (403) as they contain Totag but no Route header.
So, as a workaround, I will move the section of CANCEL before the loose-routing section. I expect it will work, but I would like to be sure that Kamailio (1.5) will not react due to the Totag of the CANCEL (it shouldn't IMHO as the Totag has no relationship with the INVITE transaction being cancelled).
Thanks a lot.
