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

Identifying a Particular Call
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:
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 serial number
The VCS web UI does
not use the call ID
number. Calls are
identified using their call
serial number only.
