OverSIP
WEB UNDER CONSTRUCTION: The code is stable and working. This web page and documentation is not... please wait a bit.
OverSIP is an async SIP proxy/server programmable in Ruby language.
Some features of OverSIP are:
- SIP transports: UDP, TCP, TLS and WebSocket.
- Full IPv4 and IPv6 support.

- RFC 5626: OverSIP is a perfect Outbound EDGE proxy, including an integrated STUN server.
- Fully programmable in Ruby language (make SIP easy).
- Fast and efficient: OverSIP core is coded in C language.
OverSIP is build on top of EventMachine async library which follows the Reactor Pattern design, allowing thousands of concurrent connections and requests in a never-blocking fashion.
