Standard ECMA-269

Standard ECMA-269
Services for Computer Supported Telecommunications Applications (CSTA) Phase III

9^th edition (December 2011)

This Standard specifies an interface and services between two entities that request and provide communication services (e.g. Applications, middleware, PBX, IP-PBX, Softswitch, phone, softphone, software devices).

CSTA operates with existing interfaces, so that differences among various existing interfaces are hidden.

Services defined in this Standard allow functional integration between a computing network and a telecommunications network.

This Standard is part of a suite of CSTA Standards and Technical Reports. See documentation.
