style='font-size:10.0pt;font-family:Arial;color:navy'>Just consider the scenario
where some connections/calls has no BYE (say because one of the UA fails, etc).
This scenario illustrates the miscount opportunity. This can be avoided only if
You count the RTP streams on a RTPProxy configuration. In the case of such a UA
fail, the sessions runs on a time-out and after that the counter would be ‘automagically’
decremented, but in the meantime the user could not receive calls, even if it
is ‘on-hook’.<o:p></o:p></span></font></p>

<br>
the dialog module functionality is yet simple - it can monitor the call <br>
(catching BYEs and other sequential requests); if no BYE is received, <br>
the dialog will expire after a defined timeout.<br>
<br>
it can count the number of calls, but globally and not per user.<br>
