GrandDialer

Seems like a great tool, HOWEVER .. doesn't work if you can't gain access to the (username and password), acquired by Google in beta phase, not every one can just sign up.

I have a GrandCentral phone number that I use quite a bit - I prefer to give this number out to most people instead of my cell or home numbers. Up until now, it's strictly been for receiving calls, and I've had to block outgoing calls on my cell phone with the *67 code if I don't want the person I'm calling to know my number. But now, GrandDialer makes it possible for you to use your GrandCentral number to make calls from your iPhone so that number appears in the Caller ID display of the person you're calling. Brilliant!

The main view when you open the app is a dial pad, just like the one you see in the iPhone's built-in phone application, though this one has a green cast to it. Flanking the Call button at the bottom is a Settings button on the left and a delete button on the right. At the bottom, you can toggle easily between the dial pad and your full Contacts list - very handy!

Set-up is fairly easy, but there is one area that could use some clarification. When you go to Settings, you enter your GrandCentral user name and password, and then enter phone numbers. What you need to enter here is your iPhone's phone number (and any other numbers you want to be able to use, like your home number), NOT your GrandCentral number. If there was just one sentence explaining this in the section where you fill in these numbers, I think it would prevent a lot of confusion.

GrandDialer does not actually make the phone call from your iPhone and then somehow mask the call. It routes your call request through GrandCentral's servers, and when the call is connected, your iPhone will ring. When you pick up, you'll hear the line ringing just as if you'd dialed the call from your iPhone directly. I've used this only where I've had very good signal strength so far, and it goes very quickly through the process of logging in to your GrandCentral account and sending the dial request to the point where your iPhone rings, in 10 to 15 seconds, if that.

If you have a GrandCentral account and you've been looking for a way to be able to use it for outgoing calls, this is the perfect app for you. And, it's free! How much better could it get?
