Hi Rahul,
/if($var(client1)!="null") /should be /if($var(client1)!="$null")/
even in the last IF, the double-quotes have to be removed around "$null" -- just compare with $null, because doublequotes there enforces a static string.
Cheers, Daniel
/. /You are doing a string comparison with the string value "/null/".
Also make sure the dialog matching is correct: append these event routes to your config file:
/event_route[dialog:start] {/ /Â Â Â Â xlog("Dialog started");/ /}/ / / /event_route[dialog:end] {/ /Â Â Â Â xlog("Dialog ended");/ /}/ / / /event_route[dialog:failed] {/ /Â Â Â Â xlog("Dialog failed");/ /}/
You should see a "dialog started" and "dialog ended" for every successful call.
Please do those modifications and see what happens.
Regards, CarlosÂ

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 ?     On Tue, Jun 3, 2014 at 2:18 PM, Carlos Ruiz DÃaz <carlos.ruizdiaz@gmail.com <mailto:carlos.ruizdiaz@gmail.com>> wrote: 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.

You should put a positive value in here in order to make sense the function call. Also, you are using for one call the ID "x.y.z.a", and for the other one $rd. Both should be the same for calls that suppose to be organized in the same group. Please take a look at the docs.
