position in the SDP packet. By default, no preferred CODEC is set and the first common
CODEC in SDP CODEC list is selected.
NOTE
A complex CODEC (G723, G726, G729) can be used as a preferred CODEC
only if it is selected in the CODECS selections on the Configuration page.

Selecting Preferred CODEC for Fax Transmissions for SIP
You can select preferred CODEC for fax transmissions. The Preferred CODEC parameter is
displayed on the CODEC Web Screen. Possible values for the parameter are G711U, G711A
and NONE. For NONE the Fax CODEC is the same as assigned for the regular voice calls.
The preferred CODEC for fax insures that G711 CODEC is used for all fax transmissions
even if a complex CODEC like G729 is selected for voice.
