6.10 Call Disconnect Parameters
The call disconnect supervision parameters are described in the table below.
Table 6-46: Call Disconnect Parameters
Parameter Description
Web/EMS: Disconnect on Dial Tone
[DisconnectOnDialTone]
Determines whether the device disconnects a call when a
dial tone is detected from the PBX.
[0] Disable = Call is not released.
[1] Enable = Call is released if dial tone is detected on
the device's FXO port (default).
Notes:
This parameter is applicable only to FXO interfaces.
This option is in addition to the mechanism that
disconnects a call when either busy or reorder tones
are detected.
Send Digit Pattern on Connect
[TelConnectCode]
Defines a digit pattern to send to the Tel side after a SIP
200 OK is received from the IP side. The digit pattern is a
pre-defined DTMF sequence that is used to indicate an
answer signal (e.g., for billing).
The valid range is 1 to 8 characters.
Note: This parameter is applicable to FXO.
Web: Disconnect on Broken Connection
EMS: Disconnect Calls on Broken
Connection
[DisconnectOnBrokenConnection]
Determines whether the device releases the call if RTP
packets are not received within a user-defined timeout.
[0] No
[1] Yes (default)
Notes:
The timeout is set by the parameter
BrokenConnectionEventTimeout.
This feature is applicable only if the RTP session is
used without Silence Compression. If Silence
Compression is enabled, the device doesn't detect a
broken RTP connection.
During a call, if the source IP address (from where the
RTP packets are sent) is changed without notifying the
device, the device filters these RTP packets. To
overcome this, set DisconnectOnBrokenConnection to
0; the device 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.
