Create a transform that converts number@<IP address of cucm> to
number@vcs.domain
number@vcs.domain
When a call is made from CUCM to Cisco VCS, the callback address is presented as number@<ip

address removed and the video domain added – this is so that the existing search rule can route the
call to CUCM:
