Version 5.2
Enables the gateway to start sending and/or receiving RTP packets to
and from remote endpoints without the need to establish a Control
session. The remote IP address is determined according to the Tel to IP
Routing table. The port is the same port as the local RTP port (set by
BaseUDPPort and the channel on which the call was received).
Valid options include:
[0] Disable = Disable (default).
[1] Transmit & Receive = send and receive RTP.
[2] Transmit Only= send RTP only.
[3] Receive Only= receive RTP only.
Alert Timeout (in seconds) (ISDN T301 timer) for outgoing calls to PSTN.
This timer is used between the time SETUP is sent to the Tel side (IP to
Tel call establishment) and CONNECT is received. If ALERT is received,
the timer is restarted.
The default is 180 seconds. The range is 1 to 600.
Note: If per trunk configuration (using TrunkPSTNAlertTimeout) is set to
other than default (refer to 'Trunk Settings' on page 178), the
PSTNAlertTimeout parameter value is overridden.
Determines the time period (in seconds) the gateway waits for an MFC
R2 Resume (Reanswer) signal once a Suspend (Clear back) signal was
received from the PBX. If this timer expires, the call is released.
Applicable only for MFC R2 CAS Brazil variant.
The valid range is 0 to 255 (in seconds). The default value is 0.
[0] No = Don't release the call.
[1] Yes = Call is released if RTP packets are not received for a
predefined timeout (default).
Notes:
If enabled, the timeout is set by the parameter
BrokenConnectionEventTimeout, in 100 msec resolution. The default
timeout is 10 seconds (BrokenConnectionEventTimeout =100).
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.
During a call, if the source IP address (from where the RTP packets
are 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.
