<p class=MsoNormal>Hello everyone,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve been struggling for a few days with OpenSIPS and
OpenXCAP and I’ve reached a certain point where I think I could really
use some help on the matter. I’ve configured a dedicated OpenSIPS instance
with pretty much the configuration mentioned in the openxcap website (<a
href="http://www.openxcap.org/wiki/Installation">http://www.openxcap.org/wiki/Installation</a>)
although I had to change it quite a bit for it to work with OpenSIPS 1.6.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve also managed with quite a bit of tweaking to
force openxcap and opensips-mi-proxy to work from non-standard directories.
I’ve used the following versions:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>python 2.6.4<o:p></o:p></p>
<p class=MsoNormal>python-application 1.2.3<o:p></o:p></p>
<p class=MsoNormal>python-gnutls 1.1.8-1<o:p></o:p></p>
<p class=MsoNormal>python-lxml 2.1.5-1<o:p></o:p></p>
<p class=MsoNormal>python-sqlobject 0.10.6<o:p></o:p></p>
<p class=MsoNormal>python-twisted-core 8.2.0-3<o:p></o:p></p>
<p class=MsoNormal>python-twisted-web 8.2.0-2<o:p></o:p></p>
<p class=MsoNormal>python-twisted-web2 8.1.0-2<o:p></o:p></p>
<p class=MsoNormal>python-zope.interface 3.5.2-1<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>On a ubuntu-server 9.10<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve also installed the python-xcaplib that came with
OpenXCAP.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However when I run the test.py suite I get 6 failures which
I don’t know what to make of them:<o:p></o:p></p>

<p class=MsoNormal>Could it be there is something wrong with my python-twisted
version? Also please note that in order to make openxcap run in fork mode and
log the errors I had to disable the Syslog error writing as mentioned also in
the ticket <a href="http://openxcap.org/ticket/136">http://openxcap.org/ticket/136</a>
which I’ve opened.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is maybe the test suite of openxcap obsolete?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>As for the OpenSIPS, I’ve modified my main
OpenSIPS server to forward PUBLISH|SUBSCRIBE|NOTIFY requests to the
Presence-OpenSIPS as follows:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>if (has_totag()) {<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'>if (loose_route()) {<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'>
…<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'>} else {<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in;text-indent:.5in'>if
(is_method("SUBSCRIBE") && $rd == "VOIP_IP") {<o:p></o:p></p>
<p class=MsoNormal>
rewritehostport("PRESENCE_SERVER:PRESENCE_PORT");<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'>
t_relay();<o:p></o:p></p>
<p class=MsoNormal>
exit;<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in;text-indent:.5in'>}<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in;text-indent:.5in'>…<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'>}<o:p></o:p></p>
<p class=MsoNormal>}<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>…<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>if( is_method("PUBLISH|SUBSCRIBE|NOTIFY") ) {<o:p></o:p></p>
<p class=MsoNormal>
rewritehostport("PRESENCE_SERVER:PRESENCE_PORT");<o:p></o:p></p>
<p class=MsoNormal>
t_relay();<o:p></o:p></p>
<p class=MsoNormal>
exit;<o:p></o:p></p>
<p class=MsoNormal>}<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Requests seem to be properly forwarded to the
Presence-OpenSIPS however I could use some confirmation that what I am doing is
correct. I see that adding on eyebeam a contact appears on the list, however it
appears grayed-out, I cannot subscribe to presence information of it.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>From time to time I also see messages on OpenSIPS-Presence
like: <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Account <null>@<null> tried to publish presence
event for <a href="sip:123456789@10.1.1.1:5060">sip:123456789@10.1.1.1:5060</a>
resulting in a SIP/2.0 403 Publishing presence events for others is forbidden<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If anyone could give out a hand, it would be greatly
appreciated! <o:p></o:p></p>
