Disconnecting calls
Disconnecting a call using the web interface
To disconnect one or more existing calls using the web interface:
1. Go to Status > Calls.
You will be taken to the Calls page.
2. If you want to confirm the details of the call, including the Call
Serial Number and Call Tag, click View. Click the back button
on your browser to return to the Calls page.
3. Select the box next to the call(s) you want to terminate and
click Disconnect.
When disconnecting a call, only the call with that Call
Serial Number will be disconnected. Other calls with the
same Call Tag but different Call Serial Number may not
be affected.

Disconnecting a call using the CLI
To disconnect an existing call using the CLI, you must first
either the call ID number or the call serial
either one of the following commands as appropriate:
xCommand DisconnectCall Call: <ID number>
•
xCommand DisconnectCall CallSerialNumber:
•
<serial number>
While it is quicker to use the call ID number to reference the call
to be disconnected, there is a risk that in the meantime the call
has already been disconnected and the call ID assigned to a
new call. For this reason, the VCS also allows you to reference
the call using the longer but unique call serial number.
When disconnecting a call, only the call with that Call
Serial Number will be disconnected. Other calls with the
same Call Tag but different Call Serial Number may not
be affected.

Limitations when disconnecting SIP calls
The call disconnection API works differently for H.323 and SIP
calls due to differences in the way the protocols work.
For H.323 calls, and interworked calls, the Disconnect
command will actually disconnect the call.
For SIP calls, the Disconnect command will cause the VCS to
release all resources used for the call and the call will appear on
the system as disconnected. However, SIP calls are peer-to-peer
and as a SIP proxy the VCS has no authority over the endpoints.
Although releasing the resources may have the side-effect
of disconnecting the SIP call, it is also possible that the call
signaling, media or both may stay up (depending on the type of
call being made). The call will not actually disconnect until the
SIP endpoints involved have also cleared their resources.
Endpoints that support
RFC 4028 [14]
timer which should cause them to clear the resources of
any hung SIP calls after a certain period of time. This
includes all TANDBERG endpoints.
