This document describes a sample configuration on MOH from Live Feed.
Cisco recommends that you have knowledge of these topics:-Cisco Unity Express
The live-feed feature is typically used to connect to a CD jukebox player. To configure MOH from a live feed, you establish
dial peer for the call
a "dummy" ephone-dn
The ephone-dn must have a phone or extension number assigned to it so that it can make and receive calls, but the number is never assigned to a physical phone. Only one live MOH feed is supported per system.
MOH is an audio stream which can be played to PSTN and VoIP G.711 or G.729 callers who are placed on hold by phones in a Cisco Unified CME system. This audio stream is intended to reassure callers that they are still connected to their calls.When the phone receiving MOH is part of a system that uses a G.729 codec, transcoding is required between G.711 and G.729. The G.711 MOH must be translated to G.729.
If you use an FXO port as the live-feed MOH interface, connect the MOH source to the FXO port using a MOD-SC cable if the MOH source has a different connector than the FXO RJ-11 connector.
MOH from a live feed is supported on the following:-
Below are some MOH resources
Flash Memory: MOH can be played from local stored files in flash memory without the requirement of external source
Live Feed: The multicast audio stream has minimal delay for local IP phones. The MOH stream for PSTN callers is delayed by a few seconds. If the live feed audio input fails, callers on hold hear silence.
Live Feed and Flash Memory: This is the preferred method if you want to use Live Feed, so that if Live Feed fails then users still have MOH from local flash memory
Note:- Cisco Unified CME 8.0 MOH enhancement allows you to create MOH groups and assign ephone extension numbers to these MOH groups to receive different media streams. Callers to the extension numbers configured under the MOH groups can listen to different MOH media streams when they are placed on hold.
MOH group defined for internal calls takes highest precedence
MOH group defined in ephone-dn takes the second highest precedence
MOH group defined in ephone-dn-template takes precedence if MOH group is not defined in ephone-dn or internal call.
Extension numbers defined in a MOH-group has the least precedence
Phones not associated with any MOH groups default to the MOH parameters defined in the moh command under telephony-service configuration mode.
