Command Remarks
5. Configure the protocol for
interworking with other
devices globally.
default entity fax protocol { t38 |
standard-t38 } [ lb-redundancy
number | hb-redundancy number ]
default entity fax protocol pcm
{ g711alaw | g711ulaw }
Optional.
By default, T.38 (namely, T.38)
protocol is used for fax. The
number of low speed and high
speed redundant packets is 0.
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.
6. Configure the maximum fax
rate globally.
default entity fax baudrate { 2400
| 4800 | 9600 | 14400 | disable
| voice }
Optional.
By default, the fax rate is
determined by the voice mode.
Note that when the disable
keyword is provided, if the call
control protocol is SIP, forwarding
of private T.38 and standard T.38
faxes will be disabled.

faculty globally.
default entity fax nsf-on
