The problem is produced by incorrect CANCELs sent out by the Cisco phone. Instead of constructing CANCEL packets the same way as the initial INVITE (as required in the SIP RfC), Cisco constructs a loose routing packet. That is just plain wrong and just one of many oddities when dealing with the Cisco VoIP stack.
Hi I have been trying to get my 7960 online with SIPGATE, Get dial tone but calls don't work. Can you post your xml file, for use with sipgate.
