Dear Cisco support team,
I have a setup where i have running cisco unified communication manager 8.5 , Publisher and subscriber.
I have Mircrosoft Exchange UM 2007 for auto attendant and voicemail.I have created a sip trunk between Microsfot UM and CUCM and a route pattern for pilot number pointing to sip trunk.
When i am calling from outside to pilot number it play the prompts but when i dialled the extension number i.e 2993 it return me the message that cannot transfer the call.
I have captured the logs and found error SIP/2.0 404 Not Found and Sending ERROR Response to the transport layer
I have also attached the error logs.Kindly check and advise me what might be the problem.
"Rerouting Calling Search Space" and "Out-Of-Dialog Refer Calling Search Space"
