MediaPack SIP User's Manual
Description
Disable [0] = DID is disabled (default).
Enable [1] = Enable DID.
If enabled, the MediaPack can be used for connection to EIA/TIA-464B DID Loop Start
lines. Both FXO (detection) and FXS (generation) are supported.
An FXO gateway dials DTMF digits after a Wink signal is detected (instead of a Dial
tone).
An FXS gateway generates the Wink signal after the detection of offhook (instead of
playing a Dial tone).
The time period (in seconds) after user hangs up the phone and before call is
disconnected (FXS). Also called regret time.
The default time is 0 seconds.
Disable [0] = Disable the polarity reversal service (default).
Enable [1] = Enable the polarity reversal service.
If the polarity reversal service is enabled, then the FXS gateway changes the line
polarity on call answer and changes it back on call release.
The FXO gateway sends a 200 OK response when polarity reversal signal is detected,
and releases a call when a second polarity reversal signal is detected.
Disable [0] = Disable the current disconnect service (default).
Enable [1] = Enable the current disconnect service.
If the current disconnect service is enabled, the FXO gateway releases a call when
current disconnect signal is detected on its port, while the FXS gateway generates a
'Current Disconnect Pulse' after a call is released from IP.
The current disconnect duration is determined by the parameter
'CurrentDisconnectDuration'. The current disconnect threshold (FXO only) is determined
by the parameter 'CurrentDisconnectDefaultThreshold'. The frequency at which the
analog line voltage is sampled is determined by the parameter
'TimeToSampleAnalogLineVoltage'.
No [0] = Don't release the call.
Yes [1] = Call is released if RTP packets are not received for a predefined timeout
(default).
Note 1: If enabled, the timeout is set by the parameter
'BrokenConnectionEventTimeout', in 100 msec resolution. The default timeout is 10
seconds: (BrokenConnectionEventTimeout =100).
Note 2: This feature is applicable only if RTP session is used without Silence
Compression. If Silence Compression is enabled, the gateway doesn't detect that the
RTP connection is broken.
Note 3: During a call, if the source IP address (from where the RTP packets were sent)
is changed without notifying the gateway, the gateway filters these RTP packets. To
overcome this issue, set 'DisconnectOnBrokenConnection=0'; the gateway doesn't
detect RTP packets arriving from the original source IP address, and switches (after 300
msec) to the RTP packets arriving from the new source IP address.
The amount of time (in 100 msec units) an RTP packet isn't received, after which a call
is disconnected.
The valid range is 1 to 1000. The default value is 100 (10 seconds).
Note 1: Applicable only if 'DisconnectOnBrokenConnection = 1'.
Note 2: Currently this feature works only if Silence Suppression is disabled.
Yes [1] = The FXO gateway disconnect calls in which silence occurs in both (call)
directions for more than 120 seconds.
No [0] = Call is not disconnected when silence is detected (default).
The silence duration can be set by the 'FarEndDisconnectSilencePeriod' parameter
(default 120).
Note: To activate this feature set DSP Template to 2 or 3.
Duration of silence period (in seconds) prior to call disconnection.
The range is 10 to 28800 (8 hours). The default is 120 seconds.
Applicable to gateways, that use DSP templates 2 or 3.
