Re: [SR-Users] cnxcc

Hello again It works perfect, I was missing "setflag(DLG_FLAG);" in my main route. Thank You very much for help.

Your example work perfect, but I have to work with mine cfg, because when I use part of Your route into my config it doesn't work like it should. I think I have some problems with dialog module, because when I start Your script I get: Apr 28 09:47:31 kamailio /usr/local/sbin/kamailio[3060]: INFO: <script>: dialog started I don't see it using my config, so it looks like dialog module doesn't work in my config file in proper way. I will let You know when I find a bug in my script. Now when I have working example it will be easier.

Maybe your problem was related to this, or maybe not. In either case, I will try to reproduce your issue later this week :).

About the script itself: I found a few inconsistencies that would have caused a problem with handing the calls even if there was no bug in the software. For example: - if you want to set the maximum amount of calls per user, use the function "cnxcc_set_max_channel" - the "call-shutdown" event route is only executed if the call runs out of credit, never for "normal call clearing". For that, use "dialog:end" or "dialog:failed" instead. - you cannot access "$var(client)" from outside the process that created it. This means that when the call is killed, "$var(client)" will have a NULL value since this event is processed by a completely different process. If you want to have this information available everywhere, use a shared memory variable instead ($sht). I created a sample script [1] that applies your requirements in a slightly different way: - it authorizes the call by checking the balance - it kills the call when the credit is over - it doesn't allow more than one call per customer [1] https://gist.github.com/caruizdiaz/11359122 In this example I used a shared memory variable, to give you an idea of how to persist the customer's ID across processes.

Try with this configuration file [1]. [1] https://gist.github.com/caruizdiaz/11323017 In summary, you can't use more than one check mechanisms. It has to be credit, time or channels, exclusively. Also, I need to test your config with Kam 4.1. I am using the trunk version. Regards, On Sat, Apr 26, 2014 at 10:23 AM, Andrzej Ciupek &lt;andrzej.ciupek(a)hotmail.com&gt; wrote: Yes.
