You have received a trouble ticket stating that users cannot place calls to the
PSTN. During testing you discover the gateway is not switching to the secondary call agent when
the primary call agent is unreachable.
What needs to be done to allow the MGCP gateway to use a different call agent if the primary
fails?
A.
The ccm-manager fallback-mgcp command needs to be added to the gateway.
B.
The ccm-manager redundant-host command needs to be added to the gateway.
C.
A Cisco Unified CallManager group that includes the secondary call agent needs to be
assigned to the gateway.
D.
The gateway needs to be defined as a non-gatekeeper-controlled intercluster trunk with the
secondary Cisco Unified CallManager defined.
