Vijetha,
As far as I know, the plugin is still needed at this point. Do you have any log that can share here so that we can get more details to try to see what was the root cause?

You should be able to get the log files from

Windows XP C:\Documents and Settings\{username}\Local Settings\Application Data\softphone.log
Windows 7/Vista C:\Users\{username}\Application Data\Local\softphone.log
Mac OS X /Users/{username}/Library/Application Support/softphone.log

Thanks,
Howard

Hi Vijetha,

Could it be a security issue ? If the sample application works in Internet Explorer, I would suggest to add the Visual force URL to the IE trusted sites. From the screen shots I think you are running Windows 7, what version of Internet Explorer ?

Hope it helps, Thomas
