Configure the Audio Codec on a UM Dial Plan

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2012-07-23

Unified Messaging (UM) servers can use one of four codecs for creating voice messages: MP3, Windows Media Audio (WMA), Group System Mobile (GSM) 06.10, and G.711 Pulse Code Modulation Linear. By default, when you create a UM dial plan, the UM dial plan uses the MP3 audio codec. However, after the UM dial plan is created, you can configure the UM dial plan to use the WMA, GSM 06.10 or G.711 PCM Linear audio codecs.
