Overview Lecture Understanding Cisco CUCM Call-Routing Architecture
Route patterns, lists and groups. Cisco CUCM uses the best match when comparing dialed digits to route patterns.
1. The dialed digits need to match a route pattern. The route pattern is connected to a route list.
2. The route list chooses the path the call will take by pointing to route groups.
3. The route group is a collection of devices that connect to the destination.
4. The call is sent from the device to the connected network.
