rate is negotiated first in accordance with the corresponding fax protocol. Here the
rate refers to the allowed maximum rate, instead of the actual rate.

Use the command to configure the gateway to use the ECM mode by
fax ecm
force.
Use the undo fax ecm
By default, the ECM mode is not used on the gateway.
The fax ecm command is used to perform the forced restriction on the gateway. If
the facsimile terminals at both ends support the ECM mode, but the non-ECM
mode has been configured on the gateway side, then the non-ECM mode is
selected. If either or both of the facsimile terminals do not support the ECM mode,
the non-ECM mode is selected. Only when the facsimile terminals on both sides
support the ECM mode and the gateway uses the ECM mode, the ECM mode will
be selected.
You must enable the ECM mode for the POTS and VoIP entities of the fax sender
and receiver in the ECM mode.
# Configure the gateway to adopt the ECM mode by force.
