Alcatel-Lucent Enterprise APIs for OmniPCX platforms


The Computer Supported Telecommunications Applications (CSTA) is a standardized ECMA protocol that enables third-party applications to control all Alcatel-Lucent OmniPCX Office Rich Communication Edition devices.

The CSTA protocol enables information exchanges to initiate services as well as to monitor and control calls and devices.


  • Supports CSTA Phase 1
    • Switching function services (answer call, clear call, conference call, divert call, etc.)
    • Status reporting services (monitor start/stop, snapshot device, etc.)
    • Bi-directional services (escape, systems status)
  • Explicit monitoring of all devices
  • SDK provides access to unique OmniPCX Office Rich Communication Edition telephony features
  • Use of private information in events and services


  • Alcatel-Lucent adds values through CSTA private information (events and services)
  • Powerful associated tools to observe system behavior, supervise system security, trace and log communication links
  • Uses a low-cost, high-bandwidth Ethernet connection
  • Core component for any Computer Telephony Integration (CTI) solution whatever the protocol level used: TAPI, XML, etc.
