Mediant 500 MSBR
Fax Bypass Payload Type
configure voip > media rtp-rtcp
> fax-bypass-payload-type
[FaxBypassPayloadType]
Defines the fax bypass RTP dynamic payload type.
The valid range is 0 to 127. The default is 102.
configure voip > media rtp-rtcp
> modem-bypass-payload-type
[ModemBypassPayloadType]
Defines the modem bypass dynamic payload type.
The range is 0 to 127. The default is 103.
volume
[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.
Fax Bypass Output Gain
configure voip > media fax-
modem > 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).
Modem Bypass Output Gain
configure voip > media fax-
modem > 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).
modem-bypass-output-gain
[FaxModemBypassBasicRTPP
acketInterval]
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.
jitter-buffer-minimum-delay
[FaxModemBypasDJBufMinDel
ay]
Defines the Jitter Buffer delay (in milliseconds) during fax and
modem bypass session.
The range is 0 to 150 msec. The default is 40.
enable-fax-modem-inband-
network-detection
[EnableFaxModemInbandNetw
orkDetection]
Enables in-band network detection related to fax/modem.

[0] = (Default) Disable.

[1] = Enable. When the 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.
