SIP User's Manual 10. Configuration Parameters Reference
Parameter Description
Web: Fax Relay Enhanced
Redundancy Depth
EMS: Enhanced Relay
Redundancy Depth
[FaxRelayEnhancedRedundancy
Depth]
Number of times that control packets are retransmitted when
using the T.38 standard.
The valid range is 0 to 4. The default value is 2.
Web: Fax Relay Redundancy
Depth
EMS: Relay Redundancy Depth
[FaxRelayRedundancyDepth]
Number of times that each fax relay payload is retransmitted to
the network.
 [0] = No redundancy (default).
 [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]
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)
 [6] 16800bps = 16.8 kbps
 [7] 19200bps = 19.2 kbps
 [8] 21600bps = 21.6 kbps
 [9] 24000bps = 24 kbps
 [10] 26400bps = 26.4 kbps
 [11] 28800bps = 28.8 kbps
 [12] 31200bps = 31.2 kbps
 [13] 33600bps = 33.6 kbps
Notes:
 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.
 Configuration above 14.4 kbps is truncated to 14.4 kbps for
non-T.38 V.34 supporting devices.
Web: Fax Relay ECM Enable
EMS: Relay ECM Enable
[FaxRelayECMEnable]
Determines whether the Error Correction Mode (ECM) mode is
used during fax relay.
 [0] Disable = ECM mode is not used during fax relay.
 [1] Enable = ECM mode is used during fax relay (default).
Web: Fax/Modem Bypass Coder
Type
EMS: Coder Type
[FaxModemBypassCoderType]
Coder used by the device when performing fax/modem bypass.
Usually, 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.
