User's Manual 69. Configuration Parameters Reference
Parameter Description

[12] 31200bps = 31.2 kbps
 [13] 33600bps = 33.6 kbps
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.
 Fax relay rates greater than 14.4 kbps are
applicable only to V.34 / T.38 fax relay. For
non-T.38 V.34 supporting devices,
configuration greater than 14.4 kbps is
truncated to 14.4 kbps.
Fax Relay ECM Enable
configure voip > media fax-modem > ecm-mode
[FaxRelayECMEnable]
Enables Error Correction Mode (ECM) mode
during fax relay.
 [0] Disable
 [1] Enable (default)
Fax/Modem Bypass 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
Fax/Modem Bypass Packing Factor
configure voip > media fax-modem > packing-
factor
[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 is 1 coder payload.
configure voip > media fax-modem > fax-modem-
telephony-events-mode
[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: The parameter is applicable only when the
fax or modem transport type is set to bypass or
Transparent-with-Events.
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
