Hi,
You need to add a host alias for 'xmpp-gw' on the machine running
openser. OpenSER does dns lookup to figure out if the destination is it,
and the R-URI has a special meaning in presence so it should be kept
with that key.
As for the contact, please change the parameter to 'sip:10.95.43.31 '
regards,
Anca

Yes, you were right. Now errors have disappeared, but
still there is not
exchange of information between servers.
In the log there are a couple of things that I find strange. The first one
is that at some point openser tries to resolve xmpp-gw, which is only the
key to mark users from the xmpp domain.
The second is that, upon receiving the subscription from the client, openser
first sends itself a subscription request, with the IP address established
in the pua_xmpp server_address parameter as Contact header value, which is
answered with a 404 response, and then it sends the same request but
changing the Contact header to the URI sip:openser.domain:5060, which is
accepted with a 200 response (see both below). Is that OK? Or should I
change that parameter to the URI, despite the instructions given in the
module documentation?

Try compiling the pua_xmpp module; it has some references in pua module
that I guess have been broken.

Thanks Anca,
I tried what you told me. The message about not sending subscribe is no
more
shown, but some new errors appear and presence
does not work yet.

Hi Pablo,
There was an optimization in pua version included in 1.3.1 release that
sometimes prevented the presence sip-xmpp gateway from working ( related
to the message "Found previous request for unlimited subscribe- do not
send subscribe") from the log.
This was removed in the svn version of the branch. I advise you to take
the pua module from svn 1.3 branch.

Hi everybody,
I have some problems to get presence information exchanged between SIP
users and xmpp ones. SIP clients (X-Lite) depend on an openser server
v1.3.1, with all necessary modules working within it, and xmpp clients
(Psi) rely on an xmpp server (ejabberd) which is in the same machine.
The link between both sip and xmpp servers is established when openser
starts, and the exchange of instant messages between sip and xmpp
users works fine. So does presence too, as long as there are only sip
users or only xmpp users involved, but it does not work between the
two “worlds” in any direction. Moreover, I do not see any packet being
exchanged between the sip and the xmpp servers when a user from one
domain subscribe to one from the other, or when they change their status.
I don’t know what the problem can be. No errors appear in the log and
I thought adding xmpp presence to openser would be straightforward
once the IM was already working.
Openser config file and part of the log file (the subscription to an
xmpp user) are attached. Hope someone can give me some clue.
Thanks in advance!
Paul
