Is anyone interested in making a calling card app that business owners like myself could benefit from? I use google voice and ringcentral for my business and I need a good calling solution. I just want a calling card app that will intercept calls just like the Google Voice App, and ask me if I want to a.) dial call using direct dial (using my droids phone number, not a calling card) b.) calling card #1 c.) calling card #2 I would think it should support at least 10 calling card numbers. And a very important feature would be for it to add the number dialed to the call log, not the calling card number. Is this doable? I know I'd be willing to pay at least $25 for it and I have 2 droid X's. There's $50 in sales already! Anyone interested?
