SIP User's Manual
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.
Determines the fax bypass RTP dynamic payload type.
The valid range is 96 to 120. The default value is 102.
Modem Bypass dynamic payload type.
The range is 0-127. The default value is 103.
Determines the fax gain control.
The range -18 to -3 corresponds 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 maximum size of a T.38 datagram that the device
can receive. This value is included in the outgoing SDP when
T.38 is used.
The valid range is 122 to 1,024. The default value is 122.
Defines the maximum size (in bytes) of the device's T.38
buffer. This value is included in the outgoing SDP when T.38
is used for fax relay over IP.
The valid range is 100 to 1,024. The default value is 1,024.
Determines when the device initiates a T.38 session for fax
transmission.

[0] Initiate T.38 on Preamble = The device to which the
called fax is connected initiates a T.38 session on receiving
Preamble signal from the fax (default).

[1] Initiate T.38 on CED = The device to which the called
fax is connected initiates a T.38 session on receiving a
CED answer tone from the fax. This option can only be
used to relay fax signals, as the device sends T.38 Re-
INVITE on detection of any fax/modem Answer tone (2100
Hz, amplitude modulated 2100 Hz, or 2100 Hz with phase
reversals). The modem signal fails when using T.38 for fax
relay.
Notes:

For this parameter to take effect, you must reset the
device.

This parameters is applicable only if the ini file parameter
IsFaxUsed is set to 1 (T.38 Relay) or 3 (Fax Fallback).
