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...

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.
