Parameter Description
Web: Fax Relay Max Rate
(bps)
EMS: Relay Max Rate
[FaxRelayMaxRate]
Defines the maximum rate (in bps) at which fax relay messages are
transmitted (outgoing calls).
 [0] 2400 = 2.4 kbps
 [1] 4800 = 4.8 kbps
 [2] 7200 = 7.2 kbps
 [3] 9600 = 9.6 kbps
 [4] 12000 = 12.0 kbps
 [5] 14400 = 14.4 kbps (default)
Note: The rate is negotiated between both sides (i.e., the device
adapts to the capabilities of the remote side). Negotiation of the T.38
maximum supported fax data rate is provided in SIP’s SDP
T38MaxBitRate parameter. The negotiated T38MaxBitRate is the
minimum rate supported between the local and remote endpoints.
Web: Fax Relay ECM
Enable
EMS: Relay ECM Enable
[FaxRelayECMEnable]
Enables Error Correction Mode (ECM) mode during fax relay.
 [0] Disable.
 [1] Enable (default).
Web: Fax/Modem Bypass
Coder Type
EMS: Coder Type
[FaxModemBypassCoderT
ype]
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= G.711 A-law 64 (default).
 [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.
The valid range is 1, 2, or 3 coder payloads. The default value is 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
[ModemBypassPayloadTy
pe]
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
[ModemBypassOutputGai
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).
