Well the link is down...

But seeing as how multiple devices can be on a single phone line (i.e. a modem and a regular phone) yet many people keep phone numbers on their address book, why not just have a simple script that activates the modem, dials the number, and hangs up - while you are holding the handset. Dead simple. Saves you the trouble of dialing. Just configure so it knows the proper dialing procedure for any given LD or local number.
 
... or you can use a BlueTooth phone, and dial from the Address Book directly. I am actually doing this. Just click a number, it asks whether i want to call or send SMS. The cool part is, it also recognizes incoming phone calls and SMS messages.

It shows who is calling, how many times the phone rang, and if I want to answer or send the caller to my voicemail. When I get SMS it behaves similarly.

It's sweet...
