hi carlos,i'm looking at the commitdiff, seems like it's just indentationsis there something i am missing?by the way, based on the module documentation, the only dependency is the dialog module, shouldn't it include the rtimer module?is it really required? what if i would only use CNXCC_MONEY and not CNXCC_TIME or CNXCC_CHANNEL? should i still loadrtimer.so before loading cnxcc.so?Kelvin ChuaOn Mon, Apr 28, 2014 at 9:13 PM, Carlos Ruiz Díaz <carlos.ruizdiaz@gmail.com> wrote:I'm glad that it worked.Please don't forget to "git pull" to update your cnxcc copy.Regards,CarlosOn Mon, Apr 28, 2014 at 3:17 AM, Andrzej Ciupek <andrzej.ciupek@hotmail.com> wrote:Hello againIt works perfect, I was missing "setflag(DLG_FLAG);" in my main route.Thank You very much for help.GreetingsAndrzej Ciupek

HelloYou are amazing !!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 startedI 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.GreetingsAndrzej Ciupek

CC: sr-users@lists.sip-router.orgKelvin,can you update your copy and try again? Maybe your problem was related to this, or maybe not. In either case, I will try to reproduce your issue later this week :).Regards,On Sun, Apr 27, 2014 at 9:27 PM, Carlos Ruiz Díaz <carlos.ruizdiaz@gmail.com> wrote:
Hi Andrzej,I found a deadlock situation using the script you posted, thanks to an unusual way of using the functions that the module exports.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
In this example I used a shared memory variable, to give you an idea of how to persist the customer's ID across processes.Regards,Carlos-On Sat, Apr 26, 2014 at 10:34 AM, Carlos Ruiz Díaz <carlos.ruizdiaz@gmail.com> wrote:
I did find a bug, using your config script, I will fix it this weekend. Try with this configuration file [1].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 <andrzej.ciupek@hotmail.com> wrote:
Yes. I want prepaid subscribers be able to create only one channel to prevent frauds for simultaneous calls.

Hi Andrzej,
are you trying to setup cnxcc to check both credit and maximum simultaneous calls?

Hi,
sorry guys, I forgot about this. I will make my own tests and post the results.
Andrzej, can you post the configuration file you are using?
