Parameter Description
FaxBypassOutputGain
For a description of this parameter, refer to ''Configuring the Fax /
Modem / CID Settings'' on page
67 .
ModemBypassOutputGain
For a description of this parameter, refer to ''Configuring the Fax /
Modem / CID Settings'' on page
67 .
T38MaxDatagram
For a description of this parameter, refer to ''Configuring the Fax /
Modem / CID Settings'' on page
67 .
T38FaxMaxBufferSize
Defines the maximum size (in bytes) of a T.38 buffer supported by
the device. 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.
DetFaxOnAnswerTone
For a description of this parameter, refer to ''SIP General
Parameters'' on page
121 .
NTEMaxDuration
Maximum time for sending Named Telephony Events (NTEs) to the
IP side, regardless of the time range when the TDM signal is
detected.
The range is -1 to 200,000,000 msec (i.e., 55 hours). The default is
-1 (i.e., NTE stops only upon detection of an End event).
EchoCancellerAggressiveNL
P
Enables or disables the Aggressive NLP at the first 0.5 second of
the call. When enabled, the echo is removed only in the first half a
second of the incoming IP signal.
ƒ
[0]
= Disable (default)
ƒ
[1]
= Enable
FaxModemBypassBasicRTP
PacketInterval
Determines the basic frame size that is used during fax / modem
bypass sessions.
ƒ
[0]
= Determined internally (default)
ƒ
[1]
= 5 msec (not recommended)
ƒ
[2]
= 10 msec
ƒ
[3]
= 20 msec
Note:
When set for 5 msec (1), the maximum number of
simultaneous channels supported is 120.
FaxModemBypassDJBufMin
Delay
Determines the Jitter Buffer delay (in milliseconds) during fax and
modem bypass session.
The range is 0 to 150 msec. The default is 40.
EnableFaxModemInbandNet
workDetection
Enables or disables in-band network detection related to
fax/modem.
ƒ
[0]
= Disable (default)
ƒ
[1]
= Enable
When this parameter is enabled on Bypass mode
(VxxTransportType = 2), a detection of an Answer Tone from the
network triggers a switch to bypass mode in addition to the local
Fax/Modem tone detections. However, only a high bit-rate coder
voice session effectively detects the Answer Tone sent by a remote
Endpoint. This can be useful when, for example, the payload of
voice and bypass is the same, allowing the originator to switch to
bypass mode as well.
