Version 6.2
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.
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.
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.
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).
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.
