The remote site needs to run multicast MOH from flash. Which statement about the MOH server configuration in Cisco Unified Communications Manager is true?

 

A.

The MOH server must be enabled for G.729 in the Cisco IP Voice Media Streaming Application service parameters.

B.

Multicast MOH can use only G.711. So you must configure the command codec G711ulaw under the call-manager-fallback configuration at the remote site router.

C.

The MOH for the remote site is a standalone configuration. No extra configuration is required on the Cisco Unified Communications Manager MOH server.
