Is there an app that turns your iphone into a real world 2-Way radio?

[iMore Question]

I have a work radio and also carry my iphone. I am looking for an app that can replace the radio and let me use my phone as a real walkie-talkie. It is a Motorola CLS 1410 radio. I do Not want Voxer or apps like that.

What's different about Voxer?
