Thanks for the reply.
Here are the steps
1) I deploy the ClicktoCall sample to Exp portal and execute the run.jsp file. The web page displays to enter Host name, Host number, Participant name and participant number.
I give all the details, in the participant number(i am specifying a VDN), please correct me if that should be different number
I have modified the run.jsp in FIX me section, makepartytopartycall method to include VPMS host name, username and pass word.
2) After entering all details when click on the call button, it throws error HTTPS STATUS 500 - Internal Server Error
An error occurred processing (jsp/run.jsp) at line 41
at line 41 is call.makecall(hostname, hostnumber, participant name, participant number)
