Parameter Description
answering side and thus, in these cases it is possible to
configure the device to start the T.38 fax session when the
CNG tone is detected by the originating side. However, this
mode is not recommended.
Note: This parameter can also be configured in an IP Profile.
Web: Fax Relay Enhanced
Redundancy Depth
EMS: Enhanced Relay
Redundancy Depth
[FaxRelayEnhancedRedunda
ncyDepth]
Defines the number of times that control packets are retransmitted
when using the T.38 standard.
The valid range is 0 to 4. The default is 0.
Web: Fax Relay Redundancy
Depth
EMS: Relay Redundancy
Depth
[FaxRelayRedundancyDepth]
Defines the number of times that each fax relay payload is
retransmitted to the network.
 [0] = (Default) No redundancy
 [1] = One packet redundancy
 [2] = Two packet redundancy
Note: This parameter is applicable only to non-V.21 packets.
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
[FaxModemBypassCoderTyp
e]
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.
The valid range is 1, 2, or 3 coder payloads. The default 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
