Parameter Description
Disconnect on Broken
Connection
[DisconnectOnBrokenConnec
tion]
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.
Broken Connection Timeout
[100 msec]
[BrokenConnectionEventTime
out]
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.
Disconnect Call on Silence
Detection
[EnableSilenceDisconnect]
Yes [1] = The 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).
Silence Detection Period [sec]
[FarEndDisconnectSilencePer
iod]
Duration of Silence period (in seconds) for call disconnection.
The range is 10 to 28800 (8 hours). The default is 120 seconds.
Note: Applicable to gateways that use DSP templates 2 or 3.
Silence Detection Method
[FarEndDisconnectSilenceMe
thod]
Silence detection method.
None [0] = Silence detection option is disabled.
Packets Count [1] = According to packet count.
Voice/Energy Detectors [2] = According to energy and voice detectors
(default).
All [3] = According to packet count and energy / voice detectors.
Send Digit Pattern on Connect
[TelConnectCode]
Defines a digit pattern that is sent to the Tel side after 200 OK is received from
the IP side. The digit pattern is a predefined DTMF sequence that is used to
indicate an answer signal (e.g., for billing purposes). Applicable only to FXS
modules.
The valid range is 1 to 8 characters.
CDR and Debug
CDR Server IP Address
[CDRSyslogServerIP]
Destination IP address for CDR logs.
Enter the IP address in dotted format notation, for example 192.10.1.255.
The default value is null string that causes the CDR messages to be sent with
all Syslog messages.
Note: The CDR messages are sent to UDP port 514 (default Syslog port).
CDR Report Level
[CDRReportLevel]
None [0] = Call Detail Recording (CDR) information isn’t sent to the Syslog
server (default).
End Call [1] = CDR information is sent to the Syslog server at end of each
Call.
Start & End Call [2] = CDR information is sent to the Syslog server at the start
and at the end of each Call.
The CDR Syslog message complies with RFC 3161 and is identified by:
Facility = 17 (local1) and Severity = 6 (Informational).
