How does a MGCP CALL AGENT route calls?

MGCP gateways delegate all call intelligence to CUCM as the call agent, meaning the gateway itself performs no independent routing decisions. Route patterns defined in CUCM match dialed digit strings and direct calls through the appropriate MGCP-controlled gateway, making route patterns the core routing mechanism for MGCP call flows.

A directory number identifies a specific endpoint or line but is not the mechanism used by the MGCP call agent to route outbound or transit calls.

A route list is a subordinate component nested inside a route pattern that orders route groups - it does not independently route calls without a parent route pattern.

Wildcard patterns are digit-matching syntax elements used within route pattern definitions, not a standalone routing construct separate from route patterns.
