How I can have the web page refreshed which will have the extension’s credentials stored on it and when the call arrives to the extension it will show the caller’s information .
Eg: i have logged in with username and password same as that on the extension on a website www.abc.com and I am storing that credentials into some variable, here i need to get and alarm when calls reaches the extension.
open a web page with the phone number as a parameter.
but this page which will show extension detail, you will need to create by your self or use some CRM.
