ENV: Cisco CallManager 5.0(4) with one sip trunk connecting one sip server.
One user registered to the sip server call the number 8911 which is DN on the CM and attached on cisco 7905 phone, registering on the CM.
Because of my sip server initiating invite messaged like this format in the sip request-line:
Problem arises, the CM can not locate the DN 8911 so it response the error code "404 not found".
How can I make CM to recognise the number 8911 is right the 7905 phone and ring the 7905 phone?
Comparison: If invite message like " [email protected] ", 192.168.15.166 is the CM ip address, the 7905 phone can ring and call set up.
