Audio Codecs
This feature allows you to specify a codec to which you can switch to during an active call. You
can use the Preferences menu to modify the order of preference of the codecs between

You can select an audio codec by name during a call, or while the handset is idle. The Audio
Codecs feature also gives you control over the audio configuration that is used for inbound
and outbound calls.
To change the codec while on the call, select Audio > Change codec, and then press OK.
The following context-sensitive soft keys are available on the Audio Codes page:
Ok — to view the Audio Codec Selection screen.
Back — to return to the previous screen.
