CSTA
CSTA (Computer Supported Telecommunications Applications) is the only globally accepted standard for 3rd Party CTI applications.
What is CSTA ?
CSTA is an abstraction layer for telecommunication applications:
- Independent of underlying signaling protocols
- H.323
- SIP
- Analog
- T1
- ISDN
- etc.
- Independent of devices
- Intelligent endpoints (Like SIP workpoints)
- Low-function / Stimulus devices
- SIP Signaling models
- 3rd Party Call Control (3PCC) versus Peer to Peer (P2P)
- Operates equally well in different environments:
- 1st Party call control
- 3rd Party call control1st party call control
- Basic call model standardized in 1992 –continually refined and enhanced based upon significant industry implementation experiences, new protocols, etc.
Design goal to enhance application portability across CSTA implementations: •Specifies normalized call model and behavior •Complete functional definition of each service •Specific conformance criteria
