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.
Regards,
Carlos
