SIP Route Pattern

A CUCM pattern that routes calls by domain or IP address, or by ILS route string, to a SIP trunk.

Definition

SIP route patterns enable URI dialing: a domain route pattern such as partner.com routes any URI with that host portion to a specified SIP trunk. They are also used with ILS route strings to route learned patterns to a Session Management Edition or other cluster. Like other patterns, they are placed in partitions and controlled by CSS.

Example

A SIP route pattern for *.example.net sends all URI calls for that domain to the Expressway-C trunk.

Exam tip

URI calls do not use numeric route patterns; they need SIP route patterns matching the domain.
