Sometimes, I use my cell phone to call someone because it simplifies the process. My iPhone has all 600+ contacts in my address book in it; looking up a number there and dialing gets me talking to someone faster than looking up the number (on the phone or on my computer) and manually dialing the house phone. I can’t be the only person who does this. Trouble is, my office is on the first floor of a 3-story building, and my house is sheathed in metal, so my cell doesn’t work all that well in here.

The upshot is that I’ve often wished for a way to click a number in my address book and have it be dialed automatically. This used to be pretty common, when we all used modems, but who has a modem anymore?

Well, thanks to their sponsorship of Mac-blogger John Gruber over at Daring Fireball, I just discovered Dialectic. I tell it to dial any number from my address book, and sets up a connection using my Vonage account; my phone rings, I answer, and then other side starts ringing. How cool is that?

Even better: It plays nicely with Quicksilver, so talking to someone is never more than a couple keystrokes away. This is awesome.

It’s not just Vonage; this thing’ll work with damn near anything (Bluetooth cells, landlines, Asterisk systems, BroadVoice, CallVantage, CiscoIP, countless softphones like Skype, etc). It’s not free, but it’s cheap enough ($25) that I’m almost certain to buy it.

Oh, yeah: It’s Mac-only. Suck it, Windows dorks. LOL.
