Let me a question: Why SIP people is interested in interoperate with XMPP while the opposite is not true?
Inaki. Do google before stating things like this ;-)
THe XMPP people have written drafts about SIP XMPP interoperability but have gotten almost no response from the SIP crowds... http://xmpp.org/internet-drafts/draft-saintandre-sip-xmpp-core-01.html http://xmpp.org/internet-drafts/draft-saintandre-sip-xmpp-groupchat-01.html http://xmpp.org/internet-drafts/draft-saintandre-sip-xmpp-media-01.html
Now, check the SIP forum. How many times do they mention XMPP?
You are right, sorry. Anyhow, how you ever seen a XMPP server integrating some kind of interoperability/gateway with SIP? In Kamailio/*SER we have some attemps to interoperate with XMPP world.
Daniel and I hosted a seminar about that in Paris a few years ago, and learned a lot. It's hard to integrate them.
A very simple thing:
- In SIP you can send a Subscribe with Expires:0 to "query" the server about the current state of a URI. - In XMPP, the server doesn't have a state for anything. It's just a message router.
I think that's why the SIXPAC group is focusing on client-based solutions instead of trying to handle interoperability on the server side.
