I need your help i have been configured my exchange um server and call manager as the following topic
but when i tried to dial exchange polit number i got busy tone.
Post the SIP dialog and identify the calling/called party numbers, as well as the IPs of CUCM and the Exchange UM role server. We'll see if we can spot an issue and provide suggestions to address it if CUCM is at fault.
Route Pattern Configuration
The Inbound Calls, Calling Search Space is < None >. Assuming yoru DNs and such are in partitions, you need a CSS and a reset of the trunk.

I changed it but still same issue.
NOT THE CORRECT SETTING
That's the Incoming Calling Party Settings section, not Inbound Calls as I stated.
