Asterisk Tutorial / Learning Guide

[zrabid]

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.

for more up to date details. (Even the paid for versions of The Definitive Guide are quite old now, so you will need the wiki to fill in current details for those.)
