How do I change the caller-ID I see when Zenofon calls me back?

Zenofon allows you to pick the caller-ID that shows up when you trigger a callback to yourself. In the "numbers you call from", in "your originating numbers" box, you can choose what number shows up when you trigger a callback from Zenofon. Either click "add a new number" or, on a number you already added, which will take you to the provisioning page, "edit your originating numbers". There are three fields there. The one on the left is the number you call from. The one on the right is the number you want to be called back with. After you add it, try it by triggering a callback to yourself. Dial 215-399-9293 and hang up at the bip bip sound. Zenofon will call you back on the number you called from with the caller-ID you just chose.
