Dialogue is a new app available in the Mac App Store that allows you to pair your iPhone, or another smartphone, to your Mac via Bluetooth. Once paired you can answer calls on your Mac as well as record them.
When someone calls you, you can choose to answer the call via your Mac or through your actual phone. Dialogue simply runs in the background on your Mac. You can access it through the menu bar tray as well. Clicking on it while not in a call allows you to search for a contact and initiate a call through your iPhone or other smartphone. Since Dialogue works through Bluetooth, most smartphones will be supported that have Bluetooth capability.
I've made a few calls with Dialogue and while it does what it says it does, call quality wasn't so great over built-in speakers. Plugging in headphones seems to remedy the problem but it'd be nice to see some kind of update to improve call quality over built-in speakers. I know that I don't always have a pair of headphones plugged in or within arm's length so that could be a potential issues for users that feel the same way.
I do however see myself using Dialogue when my phone isn't around my computer but within Bluetooth range and need to make a quick call. The recording feature could also be beneficial for calls that you need to remember information from, such as conference calls.
If you happen to give Dialogue a try, let us know about your experiences in the comments.
