Description This command is used to perform the forced limitation at the gateway. If the facsimile
terminals at both ends support ECM mode, but the non-ECM mode has been
configured at the gateway, then the non-ECM mode is selected. If one or two of the
facsimile terminals at both ends do not support the ECM mode, the non-ECM mode
is selected. Only when the facsimile terminals at both ends support the ECM mode,
and the gateway doesn’t perform the forced limitation to enable the non-ECM mode,
is the ECM mode selected.
You must enable ECM mode for the POTS and VoIP entities corresponding to the fax
sender and receiver in ECM mode.
