I am having an issue with some phones that can not use a SIP tie trunk between 2 CM's we have. They are setup with the same COR...using same Route Pattern...going out same SIP tie trunk. Yet - I am receiving a 404 Not found (No route available) on some of my stations. Why are some being blocked and some being passed? I have attached a screen shot of a successful and non-successful trace. Trace on the left you will see the call being blocked...on the right - the SIP/tie trunk allows the call to proceed to the other CM (getting the 180 ringing response).
Please help.
thanks
Robert
