So I have many Cisco 7960's that are running the latest 5.1 Cisco SIP code and I cannot get the phones to talk/RTP to each other. jtodd has had this problem in the past with the 186's. Just wondering if anyone has a reason why "Cisco sometimes poop on reinvite" is the Cisco code broke? if so we can push on Cisco to fix it. the U is a MAJOR Cisco shop so we have some puhs there. if its * code, I will offer up anything (within reason) to work this out. This prob would be a major issue in rolling * out further if every call HAS to go thru the * server fro bridging. Do other SIP hardsets have this problem? sniff you calls to another SIP hardset and check ot see if RTP is coming from the * server of the other phone? Thanks for any info I can get on this Dave P
