更改音频编解码器Change the audio codec

统一消息可以使用四个编解码器其中之一来创建语音邮件:MP3、Windows Media Audio (WMA)、Group System Mobile (GSM) 06.10 和 G.711 Pulse Code Modulation (PCM) Linear。默认情况下,在创建统一消息 (UM) 拨号计划时,UM 拨号计划使用 MP3 音频编解码器录制语音邮件。MP3 音频格式是跨多个操作系统、电子邮件客户端和 MP3 播放器使用的常用音频格式。在创建 UM 拨号计划之后,可以将 UM 拨号计划配置为使用其他音频格式之一(包括 WMA、GSM 06.10 或 G.711 PCM Linear 音频编解码器)。若要收听语音邮件,移动电话或计算机必须安装兼容的音频软件应用程序。Unified Messaging can use one of four codecs for creating voice mail messages: MP3, Windows Media Audio (WMA), Group System Mobile (GSM) 06.10, and G.711 Pulse Code Modulation (PCM) Linear. By default, when you create a Unified Messaging (UM) dial plan, the UM dial plan uses the MP3 audio codec to record voice messages. The MP3 audio format is a popular audio format that is used across multiple operating systems, email clients, and MP3 players. After the UM dial plan is created, you can configure the UM dial plan to use one of the other audio formats including the WMA, GSM 06.10, or G.711 PCM Linear audio codecs. To listen to the voice message, a mobile phone or computer must have a compatible audio software application installed.
