Hello,
There is something missing in your configuration file. See econfig
example from version 1.3 (etc/openser.cfg, line 214). You should add
something like this on the else branch for in dialog requests:
if (is_method("SUBSCRIBE|NOTIFY") && ($rd ==
"your.server.ip.address"|
$rd=="xmpp-gw"))
{
# in-dialog subscribe requests
route(2);
exit;
}
The way you have it now, all in dialog requests are not allowed, that is
all Notifies and the in dialog Subscribes.
regards,

Hi again,
Sorry about the delay and thanks for your support. I did so, but it still
does not work. The fact is that the subscription to the XMPP user is sent
from the SIP user and reaches openser, which sends back a notify request
with no presence information at all. In between there is not exchange of
information with the XMPP either.
Then openser sends itself the couple of subscribe requests mentioned in my
later post (now both with sip:10.95.43.31 as contact header), the first of
which is rejected (due to the to-tag, I suppose), while the second one is
accepted. As a result of that request, a notify is sent towards itself, but
it is rejected with a 404 Not Here response. This one do carry some presence
information, but nothing interesting:
Content-Type: application/watcherinfo+xml
<?xml version="1.0"?>
<watcherinfo xmlns="urn:ietf:params:xml:ns:watcherinfo"
version="0"
state="full">
<watcher-list resource="sip:pge354*xmpp-domain@xmpp-gw"
package="presence"/>
</watcherinfo>
Let me know whether that behaviour is the expected one or not, and what the
reason could be for it not to work (see log attached).
Regards,
Pablo

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

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!
