  • The SOAP- and REST-based Web services enable access to a rich set of communications capabilities, including third party call control, call notification, presence, messaging and media.
  • The Web services primarily provide developer interfaces to Avaya Aura, but can also interface with Avaya CS 1000, Cisco Unified Communications Manager and Tandberg VCS.
