[General] VoIP For Home Usage

Asterisk resolves my domain name when putting it in externip so I
don't need to define an IP.

I was just curious on how you had it update it :) (In case I needed it
in the future)

Today I went to dewaniya and tried to connect to my PBX from there but
it didn't work :/ I get a time-out on the connection.
