Edson,
as the dialog module *just* keeps the dialog state based on external
triggers (received messages for the moment), I was thinking that in the
future the module may use as trigger information from rtpproxy regarding
the RTP stream; it will be able to detect dialog termination based on
RTP stream even if the BYE is missing.....
that's just a thought of mine on the topic....

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’.

*Subject:* Re: [Users] limiting number of calls
Hi bogdan,
Thanks for the reply...
My requirement is as follows:
- I want to limit the number of incoming calls per user can receive.
- I think, it is possible using the avpops module. But can someone
please give me a hint on where to start to implement this.
- Now since the dialogue module is out, I dont think there wud be a
problem of missing byes as it will terminate the session after a
certain timeout.
- Is it possible in openser script to somehow set a counter.
- for eg. the counter will be set to 2 when any user receives a call
and it will be decremented when the same user receives a call again,
and when the count for that user is 0, he will receive no more calls.
- This counter has to be enabled on a per user basis.
- Please let me know if this is possible.
- I need to achieve this because otherwise any user can have an 8 port
or 24 port gateway registered with my openser and receive so many
calls at the same time. I want to avoid this happening.
thanks in advance......

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

Hi,
how can the dialog module help prevent the issue of missing
BYEs?? Is
dialog module capable of monitoring the sessions
going on in openser.
I also wanted to ask that if i try limiting the no. of calls that
per
user can receicve how do i match the invite with
the byes.
for eg: I may allow some users to have 5 incoming calls and other 2
and so on. So, I'll have to store that value in the DB table
somewhere, and when a user receives a call, this column will be
checked and the value should be decremented when he receives the
invite message.
But how do i again increment the value, when the user receives
bye. I
mean how do i write the logic to match the invite
and byes so as to
increment and decrement the simultaneous calls value.
please help me regarding this....
thanks in advance.
jayesh.
