Cannot register a third party SIP phone in the UC Endpoint lab

I have been using the UC Endpoint lab to create a third party SIP phone.

I am able to login to the VPN and connect to CUCM 10.5.2. and send SIP messages to it. The problem that I am having is the my system cannot register the phone using the assigned directory number.

 

Here is an example of the SIP transactions. CUCM is return a 404 Not Found response.

 

Is there any way to configure CUCM to register the assigned directory number for the extension?
