Aastra Web Ui - Aastra 675xi Series Release Note

Configuring Customized Codecs Using the Aastra Web UI
Use the following procedure to customize codecs for the phones using the Aastra Web UI.

Aastra Web UI

1 Click on Advanced Settings->Global SIP->Codec Preference List.
2 In the Codec Preference List 1, select a codec 9 (with its payload type) you want the phones to use. Valid values are:
All
Basic (G.711 u-law, G.711 a-law, G.729)
G722
G711u/8K
G711u/16K
G711a/8K
G711a/16K
G729
G726-16
G726-24
G726-32
G726-40
BV16 (8K)
BV32 (16K)
L16 (8K)
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.
