Configuring fax faculty transmission mode

In common fax applications, the participating fax terminals negotiate with the standard faculty (such
as V.17 and V.29 rate) by default. It means that they do not send each other non-standard facilities
(NSF) message frames. In some cases such as encrypted fax, both fax terminals adopt a (NSF to
negotiate. At the start of negotiation, both terminals first exchange NSF message frames, and then
negotiate the subsequent fax faculty for communication. NSF messages are standard T.30
messages and carry private information.
In order to use a nonstandard faculty for negotiation, the following conditions must be met:
•
Fax terminals must support nonstandard transmission mode.
•
The transmission mode must be set to a nonstandard mode in the POTS and VoIP entities for
both fax terminals.
Configuration prerequisites
VoIP configuration is completed, IP calls can be made successfully, and fax machines are connected
correctly.
