I have a phone configured in CUCM 7.0(2), it is configured with SCCP Protocol and I have configured a SIP Trunk with IP address.
When I progress a call, the fields From and To have the values shown below:
FROM: <DDI>@<IP ADDRESS CUCM>
TO: <DDI>@<IP ADDRESS TRUNK SIP>
Is it possible to change the ip address by a domain name, as in the example?
