12. Third Party Call Control
12.1. About Third Party Call Control
The Gatekeeper provides a third party call control API which enables you to place calls, disconnect calls,
or initiate a blind transfer of an existing call.
The API is provided through the command line interface; it is not available via the web interface.
12.2. Placing a Call
A call between two endpoints may be placed via the Gatekeeper by issuing the command:
xCommand Dial A B
where
A
the alias of the first endpoint
B
the alias of the second endpoint
This will return immediately and the Gatekeeper will attempt to place the call.
Like other asynchronous Gatekeeper commands, progress information may be obtained by registering
for feedback using the command:
xFeedback Register status/calls
12.3. Transferring a Call
A call may be transferred using the Gatekeeper by issuing the command:
xCommand CallTransfer Call: call_index Leg: leg_index Alias: dest
where:
call_index
the call to be transferred
leg_index
the endpoint to be disconnected
dest
the endpoint to which the call will be transferred
These indices may be determined through inspection of the output of
xStatus Calls
.
The Gatekeeper must be operating in call routed mode and call transfer must be enabled.
12.3.1. Enabling call routed mode
To enable call routed mode, either:
issue the command
xconfiguration Gatekeeper CallRouted: <On/Off>
or go to Gatekeeper Configuration -> Gatekeeper and in the Configuration section, tick the Call routed
box.
