I have it somewhat comfigured in that my software phone at home can talk to the Asterisk server at the data center. So far so good.
But - now I want to talk to a real telephone. What do I have to do to say call my cell phone? When I want to talk to the real world, what does the server connect to? Or is that a service I need to buy?
And - if I want to have 10 or so DID numbers, where do I buy them from? Need to interface to the real world.
