HI, I'm new to this forum, so go easy on me! I'm setting up a SIP endpoint for a branch site. I have got Sip fw version 3-05-2 on the phone as its the only one I can find that works. I find that the phone does not register with the CME, but it can call the skinny phone which is registered. The skinny phone gets a busy tone when trying to call the sip phone. I even manually put a sip dial peer on the system to direct to call but to no avail, also the IP-IP GW is set up to allow the calls between protocols. Can anyone tell me where I am going wrong?
Thanks in advance
