Carousel is software to connect VoIP calls to ordinary telephone lines and vice versa using one of a number of professional telephony devices. It works as a virtual FXO gateway. You install it as a service on any Windows PC. SIP protocol VoIP calls will be directed out to standard PSTN analog lines through a telephony board.

Typical Applications:
To create a 1 to 12 FXO gateway to route VoIP SIP calls to ordinary phone lines.
To run a VoIP Based PBX (eg. Axon) when no SIP Gateway or Broadband provider is available. ie. Where you want to use VoIP to route calls in a office but where all external calls are still on ordinary telephone lines.
To use an existing LAN network to route calls from a Virtual PBX.
