APPLICATIONS
Call
This is a switching relationship (generally) between two or more devices. It is also a CSTA object. In a
CSTA domain, the behavior of telephone call establishment and release can be observed and han-
dled. To characterize a call, two parameters are of use:
- Call Identifier
A call reference is automatically created by the switching domain as soon as a call appears.
- Call State
This is a list of connection states (see connection below) for all the devices involved in a particular
call.
Connection
A Connection is a relationship between a call and a device. This relationship can be both monitored
and handled. In fact, the various services provided by the CSTA protocol consist in observation and
handling of connections. A connection is defined by an identifier and a state.
- Connection Identifier
The connection identifier consists of the pairing of a call identifier with a device identifier.
• For each call, there are as many connection identifiers as there are devices connected.
- For each device, there are as many connection identifiers as there are calls connected.
- Connection state
A state is allocated to each connection, to characterize the position of the connection.
Changes in the state of the connection can be described using a states machine.
