Version 6.4
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= G.711 A-law 64 (default).
[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 value 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.
Note: This parameter is applicable only when the fax or modem
transport type is set to bypass or Transparent-with-Events.
Defines the fax bypass RTP dynamic payload type.
The valid range is 96 to 120. The default value is 102.
Defines the modem bypass dynamic payload type.
The range is 0-127. The default value is 103.
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 fax gain control.
Defines the fax bypass output gain control.
The range is -31 to +31 dB, in 1-dB steps. The default is 0 (i.e.,
no gain).
Defines the modem bypass output gain control.
The range is -31 dB to +31 dB, in 1-dB steps. The default is 0
(i.e., no gain).
Defines the basic frame size used during fax/modem bypass
sessions.

[0] = Determined internally (default)

[1] = 5 msec (not recommended)

[2] = 10 msec

[3] = 20 msec
Note: When set to 5 msec (1), the maximum number of
simultaneous channels supported is 120.
Defines the Jitter Buffer delay (in milliseconds) during fax and
modem bypass session.
The range is 0 to 150 msec. The default is 40.
