I just want to make certain I understand multicasting versus unicasting when using a .wav file as an MOH source. In an unicast environment, does each caller hear a separate instance of a file that starts at the beginning? Verus multicast, where a caller may be connected to the audio source mid-stream?
MOH is an audio stream that is 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. In Cisco CME 3.0 and later versions, you can configure the MOH audio stream as a multicast source. A Cisco Unified CME router that is configured for multicast MOH also transmits the audio stream on the physical IP interfaces of the specified router to permit access to the stream by external devices.
