Usage guidelines
If the call control protocol is SIP, this command can be used only for the originator of the fax request
(using private T.38, standard T.38, or fax pass-through protocol). When a fax request is originated using
private T.38, standard T.38, or fax pass-through protocol, the fax type is decided according to the
configurations. The receiver of the fax request responds to the originator based on the type of the fax
request, and then establishes a fax call.
You must carry out the default entity fax train-mode local command to make the configuration made by
the default entity fax local-train threshold command take effect.
