Cisco Cisco Unified Customer Voice Portal 10.5(1)

The Application Server’s Call Definition Administration pages let you:

Display the existing Call Definition information.

Modify port and Dialed Number (DNIS) settings. 

Define the Dialed Number Maximum Length if no Correlation ID Present setting.

Define the Maximum Number of Calls Allowed setting.

The number of ports you define will determine the number of calls that can be processed 
simultaneously. You should configure about 10 percent more ports than the maximum number 
of simultaneous calls you expect. The extra ports will enable the system to accommodate any 
error-related delays in releasing call resources. 
The maximum number of concurrent sessions should also be larger than the maximum number 
of simultaneous calls.

The Application Server divides Web-based calls into two groups:

Calls pre-routed with a Translation Route or Correlation ID, identified as the ID from ICM group.

Calls to be presented to ICM software as a new call, identified as the New Call group. 

ID for ICM calls result in a “Request Instructions” message being sent to ICM software, which continues 
to run the script for the call. New Call calls result in a “New Call” message being sent to ICM software 
and the call being treated as a new call, even if it had been pre-routed by ICM software.

Each group is set up with a trunk group number. The default for the New Call group is 100; the ID from 
ICM group is 200. The Application Server creates virtual port numbers for handling Web calls. These 
virtual port numbers make it easier to monitor system activity and load. The port numbers must be 
unique (that is, none can be shared between the two groups). If all the port numbers within a group are 
in use, no additional calls will be accepted within the group until a port number is freed.

ICM software might attach a Correlation ID to the Called Party Number (dialed number) when 
pre-routing a call to the ISN. The Gateway and Voice Browser pass the entire dialed number (with or 
without a Correlation ID) to the Application Server. 

You use the Dialed Number Maximum Length if no Correlation ID Present field on the Call Definitions 
page to identify whether a number has an appended Correlation ID and, if so, which portion of the 
number precedes the Correlation ID: 

If a dialed number is longer than this value, then the number has the Correlation ID appended, 
starting with the digit indicated in the Dialed Number Maximum Length if no Correlation ID Present 
field. The Application Server places the Correlation ID in a separate field and passes the information 
to ICM software, which uses it to identify the call.
