records with the account number dialed. This allows for easy filtering and accurate billing
to each department.

Configuring Music on Hold
What voice network would be complete without the sound of music coming through
handsets on hold everywhere? CME has the ability to stream Music on Hold (MoH) from
specified WAV or AU audio files that you copy to the flash memory of the router. CME
can stream this audio either in multiple unicast streams (which is more resource intensive)
or in a single multicast stream (which is less resource intensive, but requires a multicast net-
work configuration). In addition, CME can stream the MoH using G.711 or G.729 codecs.
Note:
Because the G.729 audio codec is designed for human voice, the quality of MoH
streamed using G.729 is significantly lower than MoH streamed using G.711. In addition,
CME uses transcoding DSP resources to convert the MoH to the G.729 codec. With all
these factors, using G.711 for your MoH, if at all possible, is highly recommended.
Example 7-16 configures a CME router to support multicast MoH, streaming music from
a file in flash called bonjovi.wav.
