Hi list I don't understand prepaid logic calculation, because when my credit is 0 or lees than cost per second, the call is established equal $var(i_pulse) and $var(f_pulse) how this works???? _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

Yep, assignment failed because the variables contain floating point values and Kamailio does not handle well this kind of precision. I patched the module to add the check before initiating the call, it is in master. As a way of testing your code, replace those values with integer ones, like 5 and 6, and check if the call is actually terminated or even initiated. This will give you a quick diagnosis of your routing script.

Updating the docs and using the proper terminology are pending matters on this module. Both values represent the initial and interim costs of the call, in your case, it is being billed second by second (1:1), subtracting "0.000666666666666667" every second from a pool of credit that is equal to "0.0006500000". The message that's being shown, looks like a precision loss error, which is unlikely because I used numbers even smaller than yours. Please print the values of $var(credit) and $var(cost_per_sec) before calling the cnxcc function. Furthermore, you should also consider checking your values before passing them to the function. For example: *1. check if the credit is greater than the cost per second, *before*.* /if ($var(credit) > $var(cost_per_second)) {/ /sl_send_reply("402", "payment required");/ /exit;/ /}/ There's no reason to call the function when the conditions are not met. Cnxcc will authorize the call and hang it immediately (1 second later). I may need to add this check myself inside the module. *2. make sure you are rejecting the call in case of module's error. * /if (!cnxcc_set_max_credit("$var(client)", "$var(credit)", "$var(cost_per_sec)", "$var(i_pulse)", / /"$var(f_pulse)") { / /sl_send_reply("503", "something's wrong in the server"); / /exit; / /}/ / / Regards, Carlos On Fri, May 9, 2014 at 2:45 PM, Rene Montilva &lt;renemontilva(a)gmail.com <mailto:renemontilva@gmail.com>> wrote: Hi Carlos This my kamailio config: #!ifdef CNXCC_MONEY sql_query("ca", "select * from billing.sel_customer_credit('pepe','xxxxxxx","ra"); xlog("L_INFO", "Setting up money based credit control"); if($dbr(ra=>rows)> 0){ xlog("L_INFO", "saldo:$dbr(ra=>[0,0]) y seg:$dbr(ra=>[0,1]) "); $var(credit) = $dbr(ra=>[0,0]); # 30$ of credit $var(cost_per_sec) = $dbr(ra=>[0,1]); # 1$ per sec $var(i_pulse) = "1"; # 1$ to establish the call $var(f_pulse) = "1"; # 1$ per second } sql_result_free ("ra"); # if only one call is established, that call should last 9 seconds. if (!cnxcc_set_max_credit("$var(client)", "$var(credit)", "$var(cost_per_sec)", "$var(i_pulse)", And this are the values by syslog info INFO: <script>: saldo:0.0006500000 y seg:0.000666666666666667 ERROR: cnxcc [cnxcc_mod.c:1425]: set_max_credit(): credit value must be > 0: 0.000000 On Fri, May 9, 2014 at 3:08 PM, Carlos Ruiz Díaz &lt;carlos.ruizdiaz(a)gmail.com <mailto:carlos.ruizdiaz@gmail.com>> wrote: Hi, Can you paste the code you are using, with the values that each variable contain at the moment of initiating the call?
