Action URI - click to call

Hi all,

Ive been trying to configure a "click to call" feature so that website phone numbers are clickable and will dial out from the desk phone. T46 and T48 phones.

I have downloaded a firefox addon called Telify which is supposed to do the job using an action URI.

According to the yealink admin guide I can use the following uri to get the phone to dial out:

http://user:pass@%phoneip%/servlet?number=%number%&outgoing_uri=%account%

Ive edited the url with my credentials and numbers etc. and tried this from the web browser but all I get is a big fat nothing, blank page.

I have enabled "any" under features>remote control and even tried it just with my pc IP but still nothing.

Also to add to this ive gone into directory>phone call info and tried to dial from there, it says Success but nothing happens!

any ideas of what I can try? grasping at straws now.

Thanks
