Click on Advanced Settings->Global SIP->Codec Preference List.

In the Codec Preference List 1, select a codec 9 (with its payload type) you want the phones to use. Valid values are:

All

G722

G711u/8K

G711u/16K

G711a/8K

G711a/16K

G729

G726-16

G726-24

G726-32

G726-40

L16 (16K)

Notes:

1.Setting the Codec Preference List 1 to “All” ignores the packetization interval (ptime). The packetization interval setting defaults to 30, which is the default for all codecs.

2.Setting the Codec Preference List 1 to “All” automatically sets all other codec preference fields 2 through 10 to “None”.

3.Setting the Codec Preference List 1 to “Basic” and all other codec preferences in 2 through 10 to “None”, forces the phone to use only the basic codecs as in previous releases (G.711 u-law, G.711 a-law, and G.729). If you select an additional codec to use in the codec preferences 2 through 10 fields, those codecs are added to the list of Basic codecs for the phone to use.
