The Asterisk SIP Masterclass

The Edvina Asterisk SIP Master Class!
5 days of SIP labs that will turn you into a SIP master!

SIP is the IETF standard for IP realtime communication over private networks and the Internet. It’s a platform with support for many applications beside audio and video telephony – Instant messaging, whiteboarding, games…

Asterisk is not a SIP proxy, but works alongside with the proxy and adds a lot of features to the SIP network – voicemail, PSTN gateways, follow-me scripts and application integration to name a few. If you are building a larger SIP network, then make sure you build it in a long term way, supporting future SIP applications.

This class is focusing on Asterisk in a SIP network. With a combination of theory and practical labs, you will learn how to setup and configure Asterisk and Kamailio – the Open Source SIP server – in a scalable enterprise or service provider network. We will go through various kinds of setups and give you insight in the design of real SIP networks with Asterisk running in enterprise and service provider networks. By meeting the Asterisk developer and consultant  Olle E. Johansson and the Kamailio developer Daniel-Constantin Mierla, you will also get a lot of insight into current and future features, bugs and implementation details in a way that’s hard to get otherwise.

Target group: Technical people with experience of Asterisk, working in large enterprises or with Internet Telephony Service providers.

You need to be comfortable with Linux and Asterisk before registering for this class.
