Hey all am working on a 100% ruby implementation of SIP (http://rfc.net/rfc3261.html). This is because, firstly, there doesn't seem to by any freely availabe ( yes i looked - not just another excuse to implement my very own version ) and i get to learn ruby for free. Btw - if anyone knows of any such libaray , freely availabe, let me know.
While we are on the subject of open source why the hell are there one million versions of every little thing. I guess the one of the joys of open source is the every one can go out in there own direction but damn :(
