10 Third Party Call Control

The Gatekeeper provides a third party call control API which enables you to place calls or initiate
a blind transfer of an existing call. The API is provided through the command line interface.

10.1 Placing a call

xCommand Dial may be used to place a call between two endpoints A and B. To initiate the call:
xCommand Dial A B
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:
xFeedback Register status/call

10.2 Transferring a call

A call may be transferred with the command:
xCommand CallTransfer Call: call index Leg: leg index Alias: dest
call index and leg index are used to determine which call and participant is to be transferred.
These indices may be determined through inspection of the output of xStatus Calls.
The endpoint denoted by leg index will be disconnected and replaced by the endpoint corre-
sponding to dest.
The Gatekeeper must be operating in call routed mode and call transfer must be enabled, either
with the command:
xConfiguration Services CallTransfer Mode: <On/Off>
or through the web page Gatekeeper Configuration Services shown in figure 23
Figure 23: Enabling call transfer

10.3 Disconnecting a call

An existing call may be disconnected by issuing the command:
xCommand DisconnectCall: <index>
