Refer to the exhibit.

An administrator has configured a SIP trunk between two Cisco UCM clusters. For calls that should use the trunk, the calls fail with a fast busy.

The administrator also verifies that all nodes from both clusters are powered on, and the CallManager service is running. How is this issue resolved?
