I forgot to post the response to the original subscribe, where the to-tag is
set. Now you can see that it is different from the one that appears in the
subscribe that is sent when the presence status change.

Asunto: RE: [OpenSER-Users] Problems with SIMPLE-XMPP presence
Well, I have made some tests and I think I have found what could be a wrong
behaviour of the pua_xmpp module, leading to the situation described in the
previous post. I will try to explain it better here.
Every time a XMPP client changes its presence status, pua_xmpp sends what
seems to be re-subscribes for each of its contacts belonging to the SIP
domain. The problem is that they are not linked with the original suscribes
because they don't have the same To-Tag (neither have they the same branch
in Via header, but I don't think that's important). For example:
- PREVIOUS SUBSCRIBE:
SUBSCRIBE sip:354@openser.domain SIP/2.0
Via: SIP/2.0/UDP 10.95.43.31;branch=z9hG4bKe5a9.a616d022.0
To: sip:354@openser.domain
From:
sip:pge354*xmpp.domain@xmpp-gw;tag=533cb9e91f4b999cf76861cbb9ed54ed-be94
CSeq: 10 SUBSCRIBE
Call-ID: 7d71efef-20757(a)10.95.43.31
Content-Length: 0
User-Agent: OpenSER (1.3.1-notls (i386/linux))
Max-Forwards: 70
Event: presence

Expires: 473
- NEW SUBSCRIBE AFTER STATUS CHANGE:
SUBSCRIBE sip:354@openser.domain SIP/2.0
Via: SIP/2.0/UDP 10.95.43.31;branch=z9hG4bKf5a9.e1802f23.0
To: sip:354@openser.domain;tag=10.20757.1209988007.20
From:
sip:pge354*xmpp.domain@xmpp-gw;tag=533cb9e91f4b999cf76861cbb9ed54ed-be94

As a result, the later subscribe request is rejected with a 404 Not Here
response. The pua_xmpp, upon receiving the response, sends a brand new
subscribe request, that has nothing to do with the others and is accepted by
openser.
When this is done for every contact the XMPP client has, I can see in
database how presentity table has one more row that it had before (showing
the last status change) and how active_watchers table has grown as many rows
as contacts have been involved (one for each new suscribe). And they keep
growing every time there is a change in the presence status of the XMPP
client.
So, please, let me know whether I am right and this is something to be
fixed.
Thank you,
Pablo

Thanks, Anca, that was it :)
Now presence information is shown in both the SIP and the XMPP client, but
there are still some estrange behaviours in openser.
First, when I start the SIP client with the XMPP client already online, some
kind of loop occurs, as you can see in the log attached. The following
NOTIFY message is sent again and again for a while, changing just the
from-tag, branch and call-id:
NOTIFY sip:pge354*xmpp.domain@xmpp-gw SIP/2.0

The first couple of them get the following response, but not all the others,
that get no answer:

It seems that the responses are not taken into account, or maybe it is
related with the other thing I find weird, the fact that pua and presentity
tables in Mysql database grows continuously with registries that are much
like already existing ones. Sample of the pua table:

Every time the XMPP client changes its presence state, one registry is added
to the presentity table. Sample:

How can I solve all this issues?

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,
Anca Vamanu

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

is that at

The second is that, upon receiving the subscription from the client,

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?
