Terminate Analysis on Connect

Terminates the call analysis procedure when a SIP connection indication from the network is received.  

For example, Interaction Center makes its PSTN call via SIP calls through a SIP/ISDN gateway. In this example, the SIP/ISDN gateway sends only a SIP connect message back to Interaction Center after the remote party answers the call. If call analysis is used, you would want to select Terminate Analysis On Connect, so that call analysis terminates when the SIP connect message is received.

For example, Interaction Center makes its PSTN call via SIP calls through a SIP/Analog gateway. In this example, the SIP/Analog gateway always sends a SIP connect message back to Interaction Center prematurely, before the remote party answers the call. If call analysis is used, you would want to deselect Terminate Analysis On Connect, so that call analysis continues after the SIP connect message is received.

If the connection is to a station, the Terminate Analysis On Connect configured in the station is used.

Notes: Beginning in IC 4.0 SU3, CIC terminates call analysis when it connects to remote stations. This decreases the time it takes to connect the caller to the agent at the remote station. If you want to restore the previous functionality of using call analysis when connecting to remote stations, create the Remote Station Call Analysis Answer Supervision Interaction Center server parameter, and set it to False.

You should always enable the Terminate Analysis on Connect option for a standalone fax station. Otherwise outbound faxing could fail.
