Audio Codecs Configuration

Yealink IP phones running firmware version 81 or later support a new configuration behavior for the audio codecs. It is
more effective for you to provision different IP phone modules.
The configuration parameters are different for the new configuration behavior and the older one. For more information
on old configuration behavior, refer to
istrator_Guide_V81.
The following table lists the parameters you can use to configure the audio codecs.
Parameter account.X.codec.<payload_type>.enable
It enables or disables the specified audio codec.
The name of the audio codec:
g722_1c_48kpbs-G.722.1c,(48kb/s) (only for CP920)
