They no longer sell this software. and I cannot use the drivers with xp.

I don't care if you can fax, videoconference, have multiple messages, record, interface with outlook, search email or contacts, etc.
if it does anything like that, it's a plus.

I do need however to be able to pull up a screen that depicts a phone, be able to input a phone number using a keyboard, dial that number, and talk.
I cannot pick up a receiver nor push buttons thereafter.
I use a plantronics headset that I attach to a full voice modem. this way the line is always available. The software opens and closes connections.

The phone on-screen interface has dialing buttons for mouse or keyboard access, and the call is initiated by pushing the enter key.
Also, if the phone rings, I can pull up the software phone from the background, push enter, and simply talk.

Truly hands free at all times !
So, can you recommend new products, companies or any software that can currently allow to do this in xp?

Everything that can be done with the mouse can be done with the keyboard.
