Parameter Description

[2] Enable Bypass (default)
 [3] Events Only = Transparent with Events
Note: This parameter can also be configured in an IP Profile.
Web: V.32 Modem Transport
Type
EMS: V32 Transport
[V32ModemTransportType]
Determines the V.32 modem transport type.
 [0] Disable = Disable (Transparent)
 [2] Enable Bypass (default)
 [3] Events Only = Transparent with Events
Notes:
 This parameter applies only to V.32 and V.32bis modems.
 This parameter can also be configured in an IP Profile.
Web: V.34 Modem Transport
Type
EMS: V34 Transport
[V34ModemTransportType]
Determines the V.90/V.34 modem transport type.
 [0] Disable = Disable (Transparent)
 [2] Enable Bypass (default)
 [3] Events Only = Transparent with Events
Note: This parameter can also be configured in an IP Profile.
EMS: Bell Transport Type
[BellModemTransportType]
Determines the Bell modem transport method.
 [0] = Transparent (default)
 [2] = Bypass
 [3] = Transparent with events
Web/EMS: Fax CNG Mode
[FaxCNGMode]
Determines the device's handling of fax relay upon detection of a
fax CNG tone from originating faxes.
 [0] Doesn't send T.38 Re-INVITE = (Default) SIP re-INVITE is
not sent.
 [1] Sends on CNG tone = Sends a SIP re-INVITE with T.38
parameters in SDP to the terminating fax upon detection of a
fax CNG tone, if the CNGDetectorMode parameter is set to 1.
Notes:
 This feature is applicable only if the IsFaxUsed parameter is set
to [1] or [3].
 The device also sends T.38 re-INVITE if the CNGDetectorMode
parameter is set to [2], regardless of the FaxCNGMode
parameter settings.
Web/EMS: CNG Detector
Mode
[CNGDetectorMode]
Determines whether the device detects the fax calling tone (CNG).
 [0] Disable = (Default) The originating device doesn’t detect
CNG; the CNG signal passes transparently to the remote side.
 [1] Relay = CNG is detected on the originating side. CNG
packets are sent to the remote side according to T.38 (if
IsFaxUsed = 1) and the fax session is started. A SIP Re-INVITE
message isn’t sent and the fax session starts by the terminating
device. This option is useful, for example, when the originating
device is located behind a firewall that blocks incoming T.38
packets on ports that have not yet received T.38 packets from
the internal network (i.e., originating device). To also send a
Re-INVITE message upon detection of a fax CNG tone in this
mode, set the parameter FaxCNGMode to 1.
 [2]
Events Only = CNG is detected on the originating side and a
fax session is started by the originating side using the Re-
INVITE message. Usually, T.38 fax session starts when the
‘preamble’ signal is detected by the answering side. Some SIP
devices don’t support the detection of this fax signal on the
