Sample V6000 Media Gateway Configuration File (continued)
FXSLoopCharacteristicsFilename = 'COEFFICIENT_M1K_FXS.dat'
FXOLoopCharacteristicsFilename = 'COEFFICIENT_M1K_FXO.dat'
These parameters hold the names of the characteristics files for the FXS
and FXO analog gateways. Do not modify these values.
FarEndDisconnectSilenceMethod = 0
Specify the method by which the Media Gateway detects silence during a
call. Silence is detected based on these values:
■
0 — Disabled. This is the default setting.
■
1 — Based on a specified number of silence packets that have been
transmitted or received.
■
2 — By the energy and voice detectors in the Media Gateway.
■
3 — By the number of silence packets and the energy and voice
detectors.
FarEndDisconnectSilencePeriod = 20
Specify, in seconds, the duration of a period of silence which will cause a
call to be disconnected. Minimum value is 10 seconds. Maximum value is
28800 seconds (8 hours). The default value is 20.
CallProgressTonesFilename = 'CALL_PROGRESS_M1K_NO_HOLD_US.dat'
The name of the call progress tones file. Do not modify this value.
FlashHookPeriod = 800
Set this parameter to a value between 300 and 1500 msec to control:
■
The detection of a hook flash on a telephone connected to an FXS
port
■
The generation of a hook flash on an FXO port. Note that you must
add 90 msec to this number to generate a hook flash of the desired
duration. For example, to generate a hook flash of 450 msec, set this
value to 540 msec.
ControlDiffServ = 46
Sets the Differentiated Service value in the SIP packets. The default value
is 0 (zero). The minimum and maximum values are 0 and 63.
IPDiffServ = 46
Sets the Differentiated Service Code Point value that is assigned to RTP
packets. This value is used by DiffServ compatible routers to prioritize
how packets are sent. The minimum and maximum values are 0 and 63.
