The Asterisk Masterclass

The Asterisk 5 day Masterclass!
Detailed agenda and overview

Note (January 2015): We are no longer offering this class. Please visit Digium.com for more information about Asterisk trainings.

Asterisk™, the Open Source PBX, is taking the world by storm. Asterisk makes a complete business- or carrier-class PBX out of an ordinary Linux computer, integrating with the telephony network as well as the new world of voice over IP and Internet.

However, Asterisk is not easy to learn or administer. This five-day training class will give you the knowledge and insights you need to get up to speed with your Asterisk implementation and make it production ready in no time.

The “Asterisk Masterclass” training class starts with installation and covers the most common features in Asterisk: Integration with the PSTN, the IAX2 and SIP channels for VoIP telephony and how to build a dial plan with applications like follow-me, voicemail, conferencing and call queues

Teacher – an active Asterisk developer

The teacher is Olle E. Johansson – one of the Asterisk developers with many years of experience in teaching networking. Olle is an active Asterisk developer with many years of experience of running Asterisk in enterprise and service provider networks. He’s been teaching SIP and Asterisk since early 2005 and have previously taught many classes in networking, IP, IP security, LDAP, XML and other topics.
