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.
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.
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.
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.
Enables Error Correction Mode (ECM) mode during fax relay.

[0] Disable

[1] Enable (default)
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

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.
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
