I was hopping that there were an “easier” way to do this. I also
receive a suggestion that involves the use of sst module, but to do this at
least one of the clients must support the use of Session Timers. The solution
you suggested me involves some development in the top of dialog module and yes,
this sounds interesting too.<o:p></o:p></span></font></p>

<br>
AFAIK there is no functionality that exists to do what you are trying to do.
What we had to do was write a child process within the dialog module that
stores a hash of the dialog and a list of the the contacts (ip addresses) of
the participants of the call. Then we have a timer that fires every x seconds
and we traul through the dialogs pinging the devices to see if they 'are still
there'. If any of the contacts dont respond within a predefined time, the
dialog is torn down.<br>

You should check the SST module: <a href="http://www.opensips.org/html/sst.html"
