Parameter Description
Web: Fax/Modem Bypass Coder
Type
EMS: Coder Type
[FaxModemBypassCoderType]
Determines the coder used by the device when performing
fax/modem bypass. Typically, high-bit-rate coders such as
G.711 should be used.
 [0] G.711Alaw= (Default) G.711 A-law 64
 [1] G.711Mulaw = G.711 µ-law
Web: Fax/Modem Bypass Packing
Factor
EMS: Packetization Period
[FaxModemBypassM]
Defines the number (20 msec) of coder payloads used to
generate a fax/modem bypass packet.
1 coder payload.
[FaxModemNTEMode]
Determines whether the device sends RFC 2833 ANS/ANSam
events upon detection of fax and/or modem Answer tones (i.e.,
CED tone).
 [0] = Disabled (default)
 [1] = Enabled
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 value is 102.
EMS: Modem Bypass Payload
Type
[ModemBypassPayloadType]
Defines the modem bypass dynamic payload type.
The range is 0-127. The default value 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
[FaxModemBypassBasicRTPPac
ketInterval]
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)
[FaxModemBypasDJBufMinDela
y]
Defines the Jitter Buffer delay (in milliseconds) during fax and
modem bypass session.
The range is 0 to 150 msec. The default is 40.
