Ajax has recently merged with Jake’s Brakes of Tulsa Oklahoma. Jake’s Brakes is an organization of 500 employees. The remote sales offices have 84 employees and the remainder are located at the Jake’s Brakes headquarters. Jake’s converted to a Cisco Unified Communications Manager IP phone system earlier this year. Jake’s has deployed Cisco Unified Communications Manager Express at each remote sales office and a small Cisco Unified Communications Manager cluster at the Jake’s headquarters. Currently, there are no overlapping extension numbers in the Jake’s dial plan and all calls are placed over the PSTN. The system is fully functional and includes Cisco Unity at the headquarters and Cisco Unity Express voice mail at the remote sales offices. They have two T1 s to the PSTN and a single T1 to a local service provider for Internet access. A fourth and fifth T1 will connect the Ajax campus to the new Tulsa campus. These two T1 swill carry voice and data traffic between Ajax and Jake’s.

In a distributed call processing deployment, how should a dial plan be configured to support failover if the gatekeeper rejects a call because of insufficient bandwidth?

A.
A route pattern should point to a route group to the IP WAN as the first choice and a second route group to the PSTN as a second choice.

B.
A route group should point to the gateway connected to the H.323intercluster trunk and also point to a second gateway connected to the PSTN as a second choice.

C.
A route pattern should be configured for the IP WAN and a second route pattern should be configured for the PSTN as a second choice.

D.
A route list should be configured to point at a route group to the IP WAN as the first choice and a route group to the PSTN as the second choice.
