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

Hi Rahul, /if($var(client1)!="null") /should be /if($var(client1)!="$null")/

/. /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] {/ /    xlog("Dialog started");/ /}/ / / /event_route[dialog:end] {/ /    xlog("Dialog ended");/ /}/ / / /event_route[dialog:failed] {/ /    xlog("Dialog failed");/ /}/ You should see a "dialog started" and "dialog ended" for every successful call. Please do those modifications and see what happens.

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 Díaz &lt;carlos.ruizdiaz(a)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.
