Asterisk – development overview

Releases alternate between LTS (long term support) and standard

LTS – gives 4 years of support, plus another year of security support. No new features

Standard release – shorter support, but new features can be added in each ‘dot’ release

Build your products on LTS releases of Asterisk

‘Play’ with standard releases to learn about all the new stuff

Mark made Asterisk an Open Source project

This means anyone can contribute to the progress of the project– Writing code– Fixing bugs– Test functionality– Writing documentation– Helping others– Buying Digium products, as this funds Asterisk

It also means that Asterisk has been strengthened in many directions by those that had the interest and motivation to do it

Follow the instructions to enable WebRTC support at:

wiki.asterisk.org

Enable WS,WSS transport

Enable ICE support

Some SIP settings

Add a basic dialplan

IT’S ALMOST TOO EASY!

Now for a WebRTC demo on thethe Raspberry Pi !!

What is the Raspberry Pi?

A small but fully functional ARM based computer that runs Linux

Originally developed to allow young people to start programming at a very low cost ($40 US)

uElastix is available for the Pi

23Creative Innovation – Customer Satisfaction – Continual Quality Improvement

New in Asterisk 12

Brand new SIP channel

It is PJ SIP

Uses a very modular architecture, different to chan_sip

The introduction of a REST API for Asterisk

Not a direct replacement for AMI or AGI, but something NEW!

Makes writing applications on top of Asterisk much easier for general app developers – no need to be a telephony guru any more

24Creative Innovation – Customer Satisfaction – Continual Quality Improvement

So, what do these changes mean forElastix users?

Brand new SIP channel will allow future Elastix version to:

Multiple device registrations to a single channel!!!

SIP/david-03…etc.

25Creative Innovation – Customer Satisfaction – Continual Quality Improvement

So, what do these changes mean forElastix users?

Brand new SIP channel will allow future Elastix versions to:

Add specific SIP features and functionality

…without the need for it to be added into Asterisk

…this is due to the modular way PJ SIP is implemented!

A lot of Elatix users and developers are web-friendly

The new ARI (Asterisk RESTful Interface) will facilitate more interfacing and application creation than ever before

WebRTC continued/enhanced support in Asterisk 12

Allows Elastix to become the basis of WebRTC appliances and/or gateways

26Creative Innovation – Customer Satisfaction – Continual Quality Improvement

So, what do these changes mean forElastix DEVELOPERS?

The new Asterisk REST interface:

A BRAND NEW ERA in application development

E.g. Instead of creating add-ons around app_queue…

…You can actually create a brand new app_queue

The possibilities have no limit

The Elastix user base is waiting for you to adopt Asterisk 12 and show them what you can do !!!!

27Creative Innovation – Customer Satisfaction – Continual Quality Improvement

How can you help the projects?

Asterisk and Elastix are a great combination

Digium and Palo Santo are pleased to work together

Both Open Source projects need to be funded:

Where possible, buy from Palo Santo to support Elastix

Appliances, support, etc.

Where possible, buy from Digium to support Asterisk

Phones, telephony boards, gateways, fail-over appliance, etc.

Help secure and create the future!
