I had an epiphany tonight well leaving a message for my teenage daughter. With girls it is important to say just the right thing in the right tone. Before I hung up I listen to the message and sometimes rerecord. I realized this was good practice for those calls where I am nervous about being so new. This works cell to cell you just push 1 to listen and go from there. Calling my office with Vonage just follow the directions. Test it out and see.
Just like Joe Jurek says about email, it gives you chance to think about what you said and sound your best!
