Hello,

likely you got hit by the issue fixed by:

  -
https://github.com/kamailio/kamailio/commit/25f2180999dafb807068313c4a329a16
3dd99f92

4.2 series is old and I expect this commit was not backported there.

Re: [SR-Users] [sr-dev] Planning Kamailio v5.0.4

[M S]

Hi,

There is a Kamailio sigfault issue #1277 that is also present in current
master branch. I would really appreciate if you can take a look at it
before next release, so i can upgrade my kamailio setup to v5.0 upon next
release.

Thank you.

Hi,

you can use a regex match for that as well.

if ($rs =~ "^[45].*") {

Is there any way to catch all 4XX and 5XX SIP error codes rather then 
specifying individually ie. 404, 500, 400 etc in kamailio.

Hello,

I am considering to release Kamailio v5.0.4 later this week, likely on
Wednesday or Tuesday. If you are aware of any issue in branch 5.0 which
is not yet reported on github.com/kamailio/kamailio issues tracker, then
do it as soon as possible to have a chance to look at it.

Re: [SR-Users] shared dialogs

[Charles Chance]

Hello,

Just to note, I had been looking into a similar issue before going on
holiday. I believe it may be fixed but need to do some further testing
today/tomorrow before committing. The backtrace would still be useful to
know that your issue is the same thing.

Cheers,

Charles

Yes, dialog-info+xml is for dialog states and pidf+xml should be for
user presence states, so they are different events and a publish for one
will not trigger a notify for the other. It was more or less what I
wanted to see in headers, if the subscribed events are the same, if
expires values are ok, ...

for voice you would need reports from rtpengine or rtpproxy, because
kamailio is not handling rtp (voice packets).

The see also ims_qos module, should be related in a way or another.

kamailio cannot bridge a call like freeswitch does, because kamailio
doesn't handle media stream.

The only option that you can do in kamailio to connect two phones is to
rely on REFER for doing a call transfer. See dialog module and dlg
bridge feature from there, maybe it is enough for what you want to achieve.

Daniel

according to the docs, uri_param() should work for this case. Can you
paste the first line of the request that fails with uri_param() function
so I can look at the code and see if there is any issue there?

this commit in 4.4 branch: b38167923bd13abb6bbe4d58a57ed053faa5e68e

It ensures it doesn't get truncated or gets not printable chars inside it.

Just for more clarification: if the UA is changing the URI in From/To
for requests within dialog, it makes it clear that it is not rfc2543
backward compatible, so having whatever uri value there should work.

Daniel

what version of kamailio are you using in this case? Later versions of
kamailio should not set a broken header in that case (no header with
invalid chars). So the initial header is no longer stored, and you don't
get the bad request anymore.

Anyhow, the implementation is not storing the initial value, but, iirc,
some XOR'ed value based on initial value, new value and a key. Maybe
this should be changed.

On the other hand, there is already an alternative mode to store the
initial values using dialog, see the parameters of uac module. This
should work at this moment for your situation.

Also, in many cases lately as devices are rfc3261 compliant I just
replace the headers for the initial request and for the requests within
dialog I do anonymous values, they should not be used for Caller ID and
dialog matching is done on tags (keeping the from/to uri unchanged is a
requirement to cope with rfc2543 devices).

Cheers,
Daniel

Re: [SR-Users] Presence WARNING after publish and no NOTIFY

[Yuriy Gorlichenko]

Hi
Yes but i suppose the trouble in the
pidf+xml (websockets based endpoint uses it meanwhile hardphones uses
dialog-info+ xml
As i understood it not accepts dialog states. Only presentity.

am i right?
If yes i will safe our time) if not, let me know - i will collect logs
ASAP.
