.
2. Select the existing “Route to CUCM” search rule.
Note: Search rules are used to specify the range of telephone numbers / URIs that are handled by
this neighbor CUCM. They can also be used to transform URIs before they are sent to the neighbor.
In this implementation the transforms set up in the “Create transforms” section have already made
sure that dial strings are in URI format number@vcs.domain.
Previously CUCM required dialed numbers to be in the form 3xxx@<IP address of CUCM>. A
transform converted calls to CUCM from 3xxx@vcs.domain into that format. This transform is no
longer needed.
