Fax / Modem Transparent Mode
In this mode, fax and modem signals are transferred using the current voice coder without
notifications to the user and without automatic adaptations. It's possible to use Profiles (see
) to apply certain adaptations to the channel used for fax / modem. For
example, to use the coder G.711, to set the jitter buffer optimization factor to 13, and to enable echo
cancellation for fax and disable it for modem.
➢
To configure fax / modem transparent mode:
1.
On the Fax/Modem/CID Settings page, do the following:
●
Set the 'Fax Transport Mode' parameter to
Disable
(FaxTransportMode = 0).
●
Set the 'V.21 Modem Transport Type' parameter to
Disable
(V21ModemTransportType =
0).
●
Set the 'V.22 Modem Transport Type' parameter to
Disable
(V22ModemTransportType =
0).
●
Set the 'V.23 Modem Transport Type' parameter to

●
Set the 'V.32 Modem Transport Type' parameter to
Disable
(V32ModemTransportType =
0).
●
Set the 'V.34 Modem Transport Type' parameter to

2.
Configure the [BellModemTransportType] parameter to [0] (transparent mode).
