<br>
While looking around for this xpidf I found this:<br>

<br>
So, what is the story with this xpdif ? is it still in use ? was
it replaced by pidf+xml ? as I see it died as draft.<br>

<div>I do not think the DOCTYPE is the problem here. What I see
is that when I use MI to publish this application/xpidf doc,
OpenSIPS does not want to parse the document, and if I
understand correct, this is because this type of document does
not have <tuple> XML branch.</div>
<div><br>
</div>
<div>You are right, about end-to-end, and if I configure
OpenSIPS just to relay SUBSCRIBE/NOTIFY, it should work fine.</div>
<div>But I want use OpenSIPS to be in the middle because I have
a logic in my application when it is me who change the status
(for example with web-interface)</div>
<div><br>
</div>
<div>So basically my question is, is it going to be supported by
OpenSIPS (application/xpidf)? Or as you mentioned, it is
basically the work for UA and it is not supposed to be in
OpenSIPS?</div>

You say you see the DOCTYPE line in NOTIFY packets and
this is supported by OpenSIPS ?<br>
<br>
Now, on Polycom extension - if it is something
end-2-end, it means it does not require a presence
server and everything should be between end points by
using SUBSCRIBE and NOTIFY (no PUBLISH, as this is
specific to the presence agent/server model). Am I wrong
with this ?<br>

<div>The DOCTYPE within XML is seems to be

Stas,<br>
<br>
I checked with couple of SIP UACs and I
found none using the "DOCTYPE" line the
published presence XML. So, I guess you
should simply drop such a line in your
testing.<br>
<br>
The "tuple" node is replacing your "atom"
node (at least this is what I noticed
while trying other UACs). Here is an
example of a PUBLISH xml generated by
Zoiper:<br>
<br>
<?xml version="1.0"
encoding="UTF-8"?><br>
<presence
xmlns="urn:ietf:params:xml:ns:pidf"
entity=<a href="mailto:sip:bogdan@opensips.org;transport=UDP" target="_blank">"sip:bogdan@opensips.org;transport=UDP"</a>><br>
<tuple id="bogdan" ><br>
<status><basic>open</basic><br>
</status><br>
<note>Busy</note><br>
</tuple><br>
</presence><br>
<br>
In regards to the crash, even if the XML
is not properly formated, it should not
crash - can you send me the actual MI
command + content to try to reproduce the
crash and have it fixed ?<br>
<br>
Best regards,<br>

<div dir="ltr">Hello all and Happy New

<br>
I have a problem with publishing
application/xpidf+xml (Xpidf)
presence info with OpenSIPS mi
(ver11). <br>
It seems like it is not supported.<br>
<br>
The xpidf xml body is something like
this:<br>
<br>
<?xml version="1.0"?><br>
<!DOCTYPE presence PUBLIC
"-//IETF//DTD RFCxxxx XPIDF 1.0//EN"
"xpidf.dtd"><br>
<presence><br>
<presentity uri="<a href="mailto:sip%3A244@199.182.134.149" target="_blank"></a><a href="mailto:sip:244@199.182.134.149" target="_blank">sip:244@199.182.134.149</a>;method=SUBSCRIBE"
/> <br>
<atom id="*45244*600"><br>
<address uri="sip:*45244*<a href="mailto:600@199.182.134.149" target="_blank"></a><a href="mailto:600@199.182.134.149" target="_blank">600@199.182.134.149</a>;user=ip"
priority="0.800000"><br>
<status status="open" />
<br>
<msnsubstatus
substatus="online" /><br>
</address><br>
</atom><br>
</presence><br>
<div><br>
</div>
<div>After browsing around the
source I think there are two
problems:</div>
<div>1. (in
modules/pua/add_events.c:pres_process_body)
function from
libxml2 xmlParseMemory returns
NULL when finds the
line <!DOCTYPE presence PUBLIC
"-//IETF//DTD RFCxxxx XPIDF
1.0//EN" "xpidf.dtd"></div>
<div><br>
</div>
<div>2. Another problem: when I
remove the line above from body
there is a call to another
function that is looking for
"<tuple>" node in xml (in
modules/pua/add_events.c:pres_process_body):</div>
<div>
<div>node=
xmlDocGetNodeByName(doc,
"tuple", NULL);</div>
<div><br>
</div>
</div>
<div>But there is no "tuple" in
xpidf document. So it returns
error.</div>
<div><br>
</div>
<div>3. As an experiment, I added
"<tuple>" inside my presence
body and it crashed OpenSIPS with:</div>
<div>CRITICAL:core:receive_fd: EOF
on 18<br>
</div>
<div><br>
</div>
<div>Question:<br>
</div>
<div>Is there a way to make xpidf
presence content type work with
pua_mi module?<br>
</div>
<div><br>
</div>
<div>Thank you, </div>
