Overview

About the Call Control API

The VCS provides a third party call control API. Currently this API supports the following feature:

•disconnecting a call.

Identifying a Particular Call

Each call that passes through the VCS is assigned a call ID number and a call serial number, both of which can be referenced when disconnecting a call via the CLI.

Call ID Number

The VCS assigns each call currently in progress a different call ID number. The ID numbers start at 1 and go up to the maximum number of calls allowed on that system.

Each time a call is made, the VCS will assign that call the lowest available call ID number. For example, if there is already a call in progress with an ID of 1, the next call will be assigned an ID of 2. If call 1 is then disconnected, the third call to be made will be assigned an ID of 1.

The call ID number is not therefore a unique identifier: while no two calls in progress at the same time will have the same call ID number, the same number will be assigned to more than one call over time.

Call Serial Number

The VCS assigns a unique serial number to every call passing through it. No two calls on a VCS will ever have the same serial number. However, a single call passing through a number of VCSs will be identified by a different serial number on each system.

Obtaining the Call ID/Serial Number

To control calls using the CLI, you must reference the call using either its call ID or serial number. These can be obtained using the command:

•xStatus Calls

This will return details of each call currently in progress in order of their call ID number. The second line of each entry will list the call serial number.

Call ID number

Call serial number

The VCS web UI does not use the call ID number. Calls are identified using their call serial number only.
