yeah, I had a play with that, it is a client rather than a server, but 
could probably teach me stuff to write a server

if you are going to have a play with it, you need to know about this issue:
https://code.google.com/p/php-sip/issues/detail?id=18

it randomly stops working after a few minutes of testing because of a 
simple bug, it isn't being maintained as a project.
