Hi Rahul,
sorry, I couldn't find time to do it. I will take a look tomorrow, or most possibly during the weekend.
Regards, Carlos

Hello Carlos,
Did you get a chance to look at the attached configuration file ?

Hi Carlos,
Please find attached the configuration file which I am using. Kindly refer route[CNXCC] where I have tried to put the channel limitation per SIP Server.
Thanks !

HI Carlos,
Thanks for reply.
In my case the key is SIP Server IP. My kamailio Proxy is connected to many sip server IPs say 5. I want to limit maximum channels per sip server ip. So I set max channels per sip server ip as cnxcc_set_max_channels("$var(client1)", "$var(max_chan)"); and my $var(client1) = "10.97.116.36"; is one of 5 sip servers connected to Kamalio.
Now I use your cnxcc_get_channel_count("$rd", "$var(count1)")) value(count1) to compare to the max_limit of the channels allowed for this sip server. Psuedo Variable $rd is coming correctly that is same as sips erver IP[$var(client1)]. But the problem is that cnxcc_get_channel_count("$rd", "$var(count1)")) is always setting the value 1 in $var(count1) variable even though there are more calls runnning than what was set to be max_chan (which was 100 in my case).
Any pointers to achieve this matter ?

Hi Rahul,
I don't understand your example. In that case, you are always using "10.97.116.36" as key, meaning that all calls will be hanging from same root.
If you want to use the request-uri domain part, use $rd, not the full $ru. This will of course lead to 1 call being reported always, since request-URIs tend to be different from each other.

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 !
