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!

Thanks Anca, I tried what you told me. The message about not sending subscribe is no

shown, but some new errors appear and presence does not work yet.

This was removed in the svn version of the branch. I advise you to take the pua module from svn 1.3 branch. regards, Anca Vamanu Pablo Guijarro Enríquez wrote:

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,

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?

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,

it is rejected with a 404 Not Here response. This one do carry some

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

reason could be for it not to work (see log attached).

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.

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.

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 Contact: <sip:pge354*xmpp.domain@xmpp-gw> 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 CSeq: 11 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 Contact: <sip:pge354*xmpp.domain@xmpp-gw> Expires: 3610 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.
