Asterisk Dialplan Show and Tell 1

NEW FEATURE ALERT!!

I hope to make this a regular feature on my blog. If you have an awesome dialplan that you would like to share, please let me know and I will analyze and feature it here!

My first share is the dialplan that I use for clients who need added features beyond basic calling. This includes call diverts as well as voicemail.
