Parameter Description
Note: This parameter is applicable only when the fax or modem
transport type is set to bypass or Transparent-with-Events.
Web/EMS: Fax Bypass
Payload Type
[FaxBypassPayloadType]
Defines the fax bypass RTP dynamic payload type.
The valid range is 96 to 120. The default is 102.
EMS: Modem Bypass Payload
Type
[ModemBypassPayloadType]
Defines the modem bypass dynamic payload type.
The range is 0-127. The default is 103.
EMS: Relay Volume (dBm)
[FaxModemRelayVolume]
Defines the fax gain control.
The range is -18 to -3, corresponding to -18 dBm to -3 dBm in 1-dB
steps. The default is -6 dBm fax gain control.
Web/EMS: Fax Bypass Output
Gain
[FaxBypassOutputGain]
Defines the fax bypass output gain control.
The range is -31 to +31 dB, in 1-dB steps. The default is 0 (i.e., no
gain).
Web/EMS: Modem Bypass
Output Gain
[ModemBypassOutputGain]
Defines the modem bypass output gain control.
The range is -31 dB to +31 dB, in 1-dB steps. The default is 0 (i.e.,
no gain).
EMS: Basic Packet Interval
[FaxModemBypassBasicRTP
PacketInterval]
Defines the basic frame size used during fax/modem bypass
sessions.
 [0] = (Default) Determined internally
 [1] = 5 msec (not recommended)
 [2] = 10 msec
 [3] = 20 msec
Note: When set to 5 msec (1), the maximum number of
simultaneous channels supported is 120.
EMS: Dynamic Jitter Buffer
Minimal Delay (dB)
[FaxModemBypasDJBufMin
Delay]
Defines the Jitter Buffer delay (in milliseconds) during fax and
modem bypass session.
The range is 0 to 150 msec. The default is 40.
EMS: Enable Inband Network
Detection
[EnableFaxModemInbandNet
workDetection]
Enables in-band network detection related to fax/modem.
 [0] = (Default) Disable.
 [1] = Enable. When this parameter is enabled on Bypass and
transparent with events mode (VxxTransportType is set to 2 or
3), a detection of an Answer Tone from the network triggers a
switch to bypass mode in addition to the local Fax/Modem tone
detections. However, only a high bit-rate coder voice session
effectively detects the Answer Tone sent by a remote endpoint.
This can be useful when, for example, the payload of voice and
bypass is the same, allowing the originator to switch to bypass
mode as well.
EMS: NSE Mode
[NSEMode]
Enables Cisco compatible fax and modem bypass mode.
 [0] = (Default) NSE disabled
 [1] = NSE enabled
In NSE bypass mode, the device starts using G.711 A-Law
(default) or G.711µ-Law according to the
FaxModemBypassCoderType parameter. The payload type used
with these G.711 coders is a standard one (8 for G.711 A-Law and
0 for G.711 µ-Law). The parameters defining payload type for the
'old' Bypass mode FaxBypassPayloadType and
