Asterisk Tutorial / Learning Guide

Hello asterisk world!

I am a new joiner to this amazing teleco world. I would like to know few things. Would request all of yours amazing help towards this.

1 => I would like to have a learning material which might be a pdf or an website where I can learn asterisk in layman’s terms. Where I can learn about asterisk and its modules, dialplan functions/apps and all. Please help me in regards.

2 => I would like to know whats the purpose of DAHDI? Do I need to install dahdi in every asterisk/pbx system? Or can I avoid installing DAHDI if I just make use of SIP phones and make an inbound/outbound campaign?

  1. Look for a book titled ‘Asterisk: The Future of Telephony.’

  2. Digium Asterisk Hardware Device Interface. Short answer – no cards, no DAHDI.
