Switching Solutions > Cirrus Call Control API
An Advanced Tool for Developers

The Cirrus Call Control API is a high level API that allows developers to quickly build and deploy telecommunication applications on top of a number of third party switch stacks.  The API abstracts into a common API the proprietor interfaces associated with each switch. It, also, handles all protocol specific messaging.

The Cirrus Call Control API consists of 20 high level messages that allow an application to receive calls, make calls, play prompts, collect digits, record, and conference. All data is presented in a normalized form and is protocol/switch independent. This level of abstraction allows the application developer to write an application at what is effectively a scripting layer.

Currently the Cirrus Call Control Stack has integrated with Cantata, Dialogic, Asterisk and Radvision. Protocols supported include ISUP, ISDN, DTMF, MFR1, FX0/FXS, SIP, and H.323.
