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 serial number

The VCS web UI does not use the call

ID number. Calls are identified using

their call serial number only.
