Question 64/257

You have deployed a centralized call processing solution with a multicast MOH server at your central site on a different VLAN from your Cisco Unified Communications Manager servers and IP phones. When central site users place calls on hold, dead air or silence is heard. Which two actions will resolve this issue? (Choose two.)

A. Keep the TTL at 1 for the MOH server and increase the TTL for IP multicast routing to 2 on router interfaces.

B. Increase the TTL in the configuration of the MOH server to 2 so that packets can cross the VLAN boundary.

C. Enable multicast routing on all the routers at the central site.

D. Configure ip-sparse mode on the router interfaces and increase the TTL on the routers to 2.

E. Enable multicast routing on only those router interfaces that connect the voice and MOH VLANs.

F. Decrease the TTL configuration in the Cisco Unified Communications Manager server to 0 so that the multicast packets only go to the VLAN that contains the Cisco Unified Communications Manager server and IP phones.
