Visual Dialplan Tutorials and Asterisk dial plan examples

Use some VoIP service provider, there are so many of them out there, check http://www.voip-info.org/wiki/view/VOIP+Service+Providers.
Once you open account with some of them you will get the SIP number to call directly from your Asterisk.

You really make it seem so easy with your article but I find this topic to be really something which I think I would never understand.

It seems too complicated and very broad for me. I am looking forward for your next post, I will try to get the hang of it!

I'm really glad to find your site. keep up the good work!

Following up on Sean's post, I would love a couple of database examples: How to set them up and how to query them. It appears that Visual Dial Plan has the ability to utilize a couple of database structures. Any additional information would be hugely helpful!
