CommCon 2019 034: Building a WebRTC Camera for Alexa


Sam Machin - 034: Building a WebRTC Camera for Alexa

Amazon recently released some WebRTC support within Echo devices that contain a screen. (Echo Show & Spot)
I will show you how to connect your Echo to a WebRTC client running in a browser and build your own home monitoring solution.

Amazon recently released some WebRTC support within Echo devices that contain a screen. (Echo Show & Spot) This is part of the Smart Home SDK and is primarily designed to connect devices such as video doorbells and security cameras.
Over Christmas I sat down and tried to work through this following the less than excellent documentation.
I will show you how I connected en Echo to a WebRTC client running in a browser, talk about some of the oddities of the Amazon implementation and how I got around those. The code is a mixture of Python on the server side and javascript in the browser,
We'll also cover the basics of Alexa, the SDK's and how to build your first skill as part of this.

Jöran Vinzens - 035: SITREP - Asterisk Rest - the first steps are done. Now what?

One year into an ARI based PBX and we managed to complete a Basic Call. We gave ourselves a challenge, every Dev should be able to develop a PBX feature with no prior experience about SIP, Asterisk, Kamailio and all the other things. I will show what we have come up with.

A large scale PBX based on Asterisk is not something you would do just for fun. We have a base of about 3/4 of a Million Subscribers and we are running a very large legacy Asterisk Based PBX. Sangome gave us the possibility of an RESTful, up to date platform (Asterisk ARI) and we are building a new system based on this.
We have to manage several milestones in order for us to be able to reach our goal.
First, we started with a simple playback and then went further by establishing a basic call.
Since we wanted a lot of requirements, such as scalability, easy entry for new developers etc. to be in our finished solution then it took us quite a while and along the way we learned a lot.

Some say: All roads lead to Rome. We found it is not always the same with ARI. We come across a lot dead ends due to a lack of easy documentation or examples.
I'll show you our hardest leanings and some good practise we have come up with. As well, I will give a brief overview of our soft migration path, which we think enables us to move all our features over one by one.
This talk will not go to deep into ARI but will provide a good picture on how things might come together. It will be possible to follow the talk without knowing ARI beforehand.

David Duffett - 031: Why Nerds Aren't Heard: 7 ways Geeks sabotage their own presentations & how to.

Why are some presentations so forgettable? Having something to say is one thing, but being able to say it in a way that quickly engages others, and warms them to your message, is another thing entirely. Attend this interactive presentation to identify the pitfalls, so you can avoid them next time!

Sadly, all too often presentations made by well-meaning Geeks are a catalogue of errors in terms of effectively conveying the message they wish to get out there...Of course, there are a few things that when done properly pretty much guarantee the success of a presentation!
David has boiled these things down to 7 Power Presenting Protocols (especially for Nerds) and in this session he will identify the mistakes that are often made and then offer one of the Protocols to address it.

Your presentations may never be the same again!!!!
