T.38
Using T.38 protocol to FAX.
T.38 is used for better and faster facsimile transmission. It is
recommended to enable T.38 to gain better fax quality without
setting fax and voice parameter.
Select UDP if some routers cannot use FAX by TCP.
Enable High Quality
VoiceCom90 sends the same FAX frame twice to get a high
quality of the FAX. It requires more bandwidth.
T.30
VoiceCom90 uses T.30 as the protocol for fax transmission.
The parameter settings are the same as for voice transmission.
However, enabling the fax function will consume more
network resources and will affect transmission quality.

a FAX or not.
Codec Settings
You can set the preferred codec, Jitter Buffer, Silence Detection/Suppression and Echo
Cancellation in this section.
