THIRD PARTY CTI - CSTAAPPLICATIONS
Ed. 04 7/16Réf. 3EH 21000 BSAA
DESCRIPTION OF CSTA SERVICES
The implementation of CSTA services in the Alcatel OmniOffice system uses the principle of device mo-
nitoring. Each monitoring request creates a "data stream" between the monitored system device and
the CSTA application of the CTI server which made the request. All the events of all the connections in
which the device is involved are reported by this "data stream" which is identified by a reference
(cross_ref_id). All the events carried by the "data stream" are identified by this reference, which enables
them to be routed through the CSTA application.
The CSTA services are available for the following elements:
- Alcatel multiline Reflexes sets (including DECT sets and IP Phones)
- Monoline Alcatel Reflexes sets
- Analogue Z terminals
- Virtual terminals
Nonetheless, devices not supported can be involved in communications with supported devices. In
such cases, the CSTA service requests can only be made on the supported devices.
The switching services introduced by CSTA use those offered by the system. This means that from the
viewpoint of the telephone set, the CSTA services behave in the same way as the equivalent telephone
services provided manually.
To be able to activate switching services on a device, the device must be the subject of a valid super-
vision request.
SERVICES PROVIDED
The services offered by the CSTA protocol are of four types:
- switching services enable a computer to control the switching capacity of the system. For all these
services, the server is, therefore, the system and the client is a computer on the network.
- monitoring services enable a client situated in the computing domain to receive information con-
cerning calls or system devices situated in the switching domain.
- computer services enable a client situated in the computing domain to request routing of a call.
- bi-directional services allow installation of services not defined in the protocol.
