What is the correct order for configuring call routing in Cisco Unified Communications Manager?

Question

Options

• Agateway and SIP trunk, route group, route pattern, route list
• Bgateway and SIP trunk, route list, route group, route pattern
• Cgateway and SIP trunk, route group, route list, route pattern
• Droute list, gateway and SIP trunk, route group, route pattern

• A
  8% (1)
• B
  8% (1)
• C
  85% (11)

Explanation

CUCM call routing configuration follows a strict bottom-up dependency chain. The gateway or SIP trunk must exist before it can be referenced by a Route Group. The Route Group must exist before it can be added to a Route List. The Route List must exist before a Route Pattern can point to it. Therefore the correct sequence is: (1) configure the gateway/SIP trunk as the egress point, (2) create a Route Group and add the gateway/trunk, (3) create a Route List and add the Route Group, (4) create a Route Pattern that matches dialed digits and targets the Route List. Options A and B have route pattern and route list in the wrong order relative to route group. Option D incorrectly places the route list before the gateway.
