Re: [sr-dev] Fwd: Create multiple profiles using dialog module

Hi Carlos, Sorry for coming late on this one. the ruri value in my example is '10.97.116.36' and i have tried to configure kamailio to only cater 100 simultaneous calls on this SIP Server (10.97.116.36), after that it is to send 403. Below is the sample logic from kamailio.cfg *********************************************************************************************************************** #Below lines to show an example of how I am maintaining the business for Concurrent Call Restriction route[CNXCC] { $var(client1) = "10.97.116.36"; $var(max_chan) = 100; #!ifdef CNXCC_CHANNEL xlog("L_INFO", "Setting up channel based credit control"); $var(max_chan1) = 0; $var(retcode) = cnxcc_set_max_channels("$var(client1)", "$var(max_chan)"); if ($var(retcode) == -1) { xlog("Error setting up credit control"); return; } $var(count1) = -1; if (!cnxcc_get_channel_count("$rd", "$var(count1)")) { xlog("Error getting customer's channel count"); } xlog("RAHUL : CNXCC ROUTE: $var(client1) has $var(count1) call(s)"); xlog("L_INFO", "CNXCC ROUTE: $var(client1) has $var(count1) call(s)"); if ($var(count1) == $var(max_chan1)) { xlog("Too many channels for customer"); sl_send_reply(403, "Forbidden"); exit; } #!endif ****************************************************************************************************************************************************** Now the problem that I am facing is that with multiple UACs (all with same ruri - 10.97.116.36) dialing some pstn numbers, the value of "count1" remains 1 for all cases. Hence, my purpose is defeated because the restriction is not being laid and more than 'max_chan' no. of callers are able to make the call. Could you please help me achieve this goal. Thanks !
