Configuring the Dialplan for Testing

In order to allow our phone to call other phones (or, if a multiline phone, to call itself),
we need to modify the extensions.conf file. Building on what we had in “Setting Up the
Dialplan for Some Test Calls,” add the following parts to the [internal] context:
exten => 1000,1,Verbose(1|Extension 1000)
exten => 1000,n,Dial(SIP/1000,30)
exten => 1000,n,Hangup()
If you have two phones, or multiple lines configured, you can duplicate the previous
configuration and change the 1000 to the other extension name.

Connecting to a SIP Service Provider

With the advent of Internet telephony, there has been an influx of Internet-based phone
companies springing up all over the world! This gives you a large number of choices
from which to choose. Many of these service providers allow you to connect your As-
#
terisk-based system to their networks, and some of them are even running Asterisk
themselves!
