Yes, copy/paste error, sorry. I meant to say *!=$null.*
Thank you for noticing Daniel. Carlos.

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] {*
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.
Regards, Carlos

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

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 !
