Hi Carlos,
You do need a SIP over WebSockets client (for example, an HTML5 SIP
phone) to use the WebSocket transport. sipml5, running on Google Chrome
Beta (or Canary) with the PeerConnection API enabled, works just fine
with the Kamailio WebSocket implementation without any additional
software being needed.
OverSIP is alternative SIP proxy that you could use instead of (or in
addition to Kamailio), but you do not need this at all if you just want
to connect a WebSocket client to Kamailio.
You can make calls between WebSocket clients, or you can make calls
between WebSocket clients and non-WebSocket clients using Kamailio (you
just need to make sure that the non-WebSocket clients support the
correct set of media options).
If you look in the history of the sr-dev mailing list there is a thread
between 07/07/2012 and 09/07/2012 about using the WebSocket module.
Regards,
Peter
