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 OmniPCX Enterprise devices. 
The CSTA protocol enables information exchanges to initiate services: monitor and control calls and devices; set and query features; route calls; send and receive data.


  • Supports CSTA Phase 1 and 2:
    • Switching function services (answer call, clear call, conference call, divert call, etc.)
    • Status reporting services (monitor start/stop, snapshot call, etc.)
    • Computing function services (RSI)
    • Input/output services (fast data)
    • Voice unit services (record message)
    • Bi-directional services (escape, system status)
  • Explicit monitoring of all devices
  • CSTA application correlator data is fully supported
  • Use of private information in events and services


  • Alcatel-Lucent adds value 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 used: TAPI, TSAPI, XML, etc.
