Op panel & desktop dialling

Hello everyone! I’ve been wondering for a while now, if there’s a way to make call from the desktop, using an applet of some kind, maybe the operator panel itself with some modifications…
Thing is, I have tons of number in my addressbook (shared with other people workin wih me) and I’d like very much to be able to dial them from some website of the panel, or any other programs, importing my addressbook list or something like that!!!
If anyone of you know something of the kind exists (maybe an handmade module 4 trixbox), please let me know!!
BTW, I’m not able to set the password in op panel…do I only modify the line inside /var/www/…/ op_server.vfg
with the password I like and it should work?? it doesn’t for me.
