[SR-Users] Presence Dialog not being created

[Gnaneshwar Gatla]

Hello Timo,

I have installed the patch to the kamailio source and compiled it. Thing is it does work fine to create a presentity with the obtaining the dialog-expires from the session created.
It drops down to the one last problem.

The presentity information is not deleted when the user hangs-up even before the "dialog-expires". This presence is maintained until the "Exipres" timer, for my x-lite client that's 7200secs.

I have attached the log about this scenario.

Regards
Gnani

The problem seems to stem from the dialog module: Apparently, all dialog parameters (including lifetime) are set during the creation of a dialog only after create callbacks have been executed. This is why a lifetime of zero is always available to callback functions, including the one from pua_dialoginfo, no matter what the configured lifetime is.

I have created a little patch for 3.1 that changes the dialog module such that dialog variables are set prior to calling creation callbacks. It's attached in this email -- would you mind giving it a try and see if it helps? In order to apply the patch, all you need to do is check out the 3.1 branch (unless you already did so) doing

  git clone --depth 1 -b 3.1 git://git.sip-router.org/sip-router sip-router

and apply the patch inside that directory like this:

  cd sip-router
  patch -p 1 < /patch/to/patch

Now recompile and run as usual. Please let me know if things work now.

Thanks a lot and


cheers,

--Timo
