Thanks !

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

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.
