[OpenSER-Users] Problems with SIMPLE-XMPP presence

Thu Apr 17 09:07:25 CEST 2008

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 at 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
