Hello,
you said that the publish is created by the phones in your case, not by
kamailio with pua_dialoginfo, right?
If yes, then one question for Klaus D. in this case ... the body is
build in pua_dialoginfo with the placeholder and presence_dialoginfo
expects that? I had not dug in the code yet, just double-checking here.
Thanks,
Daniel

Hello Daniel,
The problem is, that the format shown in the original email message below
isn’t original. Some space characters are deleted. I will write it in
another form:
Party A:
A-1) initial notification to a Subscribe message was without body (because
no information about the subscribed party was available)
A-2) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="4" state="full" entity[..]>
A-3) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="5" state="full" entity[..]>
A-4) second notification to a dialog state change (confirmed, PUBLISHed
with PUBLISH ad B-4 below):
<dialog-info xmlns=[..] version="1" ll" entity[..]>
Party B:
B-1) Initial notification to a Subscribe message:
<dialog-info xmlns=[..] version="00000000000" state="full"
entity[..]>
B-2) second notification to a dialog state change (confirmed, PUBLISHed
with PUBLISH ad A-2 above):
<dialog-info xmlns=[..] version="1" state="full"
entity[..]>
B-3) third notification to a dialog state change (terminated, PUBLISHed
with PUBLISH ad A-3 above):
<dialog-info xmlns=[..] version="2" state="full"
entity[..]>
B-4) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="4" state="full" entity[..]>
So here you can (should) see that the full string-length of the
placeholder is used all time and in the situations above filled with space
characters.
Regards,
Klaus

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users Hello list,
I have a special situation in which string characters of the
"root-line" of the notify-body are overwritten by Kamailio. In detail:
the root-line of the NOTIFY message sent to the subscriber looks like:
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
ll" entity="sip:117090@10.16.10.99"> instead of
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
state="full" entity="sip:117090@10.16.10.99"> In other words:
the
string state="full" is overwritten by space characters.
Is it by space
or by the versios="1"? Maybe the email body encoding ate
the spaces, above looks like one space before 'll"'.
Cheers,
Daniel
Therefore the message
is no longer "valid" and the parser of the subscriber-user agent has
problems....
The exact scenario in my use case is, that user agents can subscribe
the events "presence" and "dialog" on Kamailio. The information
about
presence and dialog-states is published to Kamailio by PUBLISH
messages from the user agents themselves. Kamailio does not have to
generate this information itself. In the following lines I have an
excerpt of the signalisation: 1) initial subscription of party A, 2)
the responded notification (without body) 3) subscription of party B
4) the responded notification (with body) 5) a publish message of the
subscribed party B with actual dialog information and 6) the
notification with body to the subscriber A.

Debug information of Kamailio and information in the source code show
that the version number "00000000000" is a placeholder only, which
should be replaced with a valid version number. However, it seems that
there is a problem in handling these strings. The version number is
replaced, but in case that the version id is only one character long,
ten space characters are inserted- overwriting other information......
Can anybody comment this problem? Is this a bug of the
presence_dialoginfo- or another module?
Thanks in advance!
Regards,
Klaus
P.S. additional information from source code an debug output of
kamailio:
notify_body.c:
[...]
/* The version must be increased for each new document and is a 32bit
int.
As the version is different for each watcher, we can not set here
the
correct value. Thus, we just put here a placeholder which will be
replaced by the correct value in the aux_body_processing callback.
Thus we have CPU intensive XML aggregation only once and can use quick
search&replace in the per-watcher aux_body_processing callback. We use
11 chracters as an signed int (although RFC says unsigned int we use
signed int as presence module stores "version" in DB as
signed int) has max. 10 characters + 1 character for the sign
