Hi,
Yes you can send the ID to the browser in whatever method you wish. First you need to have the 3CX assistant installed and the use the notify external program and in the adress that you want to call for example
http://www.whitepages.com/search/ReversePhone?full_phone=44455556666 - please note
Would become
http://www.whitepages.com/search/ReversePhone?full_phone=%callid%
That will tell internet explorer to launch this link and the assistant will change the callid with the actuall callers ID.
