Valid Range and Description
FaxModemBypassBasicRTPPa
cketInterval
Determines the basic frame size that is used during fax / modem
bypass sessions.
[0] = Determined internally (default)
[1] = 5 msec (not recommended)
[2] = 10 msec
[3] = 20 msec
Note: When set for 5 msec (1), the maximum number of
simultaneous channels supported is 120.
FaxModemBypassDJBufMinDe
lay
Determines the Jitter Buffer delay during fax and modem bypass
session.
The range is 0 to 150 msec. The default is 40.
EnableFaxModemInbandNetw
orkDetection
Enables or disables inband network detection related to
fax/modem.
[0] = Disable (default)
[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.
