Chapter 1 A800P Overview

1.1 What is Asterisk

The Definition of Asterisk is described as follows:
Asterisk is a complete PBX in software. It runs on Linux, BSD, Windows (emulated) and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in four protocols, and can interoperate with almost all standard-based telephony equipment using relatively cost-effective hardware. Asterisk provides Voicemail services with Directory, Call Conferencing, Interactive Voice Response, Call Queuing. It supports for three-way calling, caller ID services, ADSI, IAX, SIP, H323 (as both client and gateway), MGCP (call manager only) and SCCP/Skinny (voip-info.org).

Notice: You should write the destination number instead of the outgoing_number in the above dial plan. The dialplan achieves that when an extension telephone dials 200, Asterisk will transfer through channel 3 to the destination. While a call comes from PSTN line, Asterisk answers firstly, and then gets through to the extension set which connects channel 1. 
After saving your dialplan, please run "asterisk –r", then execute "reload" in the CLI. Next you are able to make calls.
