SLUG VoIP Slides

I’ve finally gotten around to putting the slides from my SLUG talk up. Funnily enough linux.conf.au has kept me pretty busy, as usual I’ll take this opportunity to just blame Pia.

You can find the slides on my presentations page, and here is a direct link to the PDF.

A couple of people have asked me which VoIP phones and ATAs I recommend. I don’t have a load of experience with different brands but have done a fair bit of research and really like the SNOM phones and the Linksys (Sipura) ATAs the best.

The main advantages of these units is that they are of fairly high quality a very good price. They are very configurable and have the advantage of being mass deployed via DHCP, TFTP and CGI based config files.

Lindsay made me do it!

While at the Waugh Partners launch party tonight, a bunch of people, mainly Lindsay asked for some details on what I’d be talking about at SLUG on Friday. I thought that was a very good question and that I should make something up 🙂

So for those that are wondering I will attempt to cover the following topics in no particular order or level of detail

  • VoIP 🙂
  • Codecs, which one should I use
  • VoIP Hardware (Phones, ATAs, ISDN and PSTN cards, Mobile Pods)
  • VoIP Providers and what they offer
  • Asterisk and what it can do
  • Beagle Internet IVR and distributed VoIP Call Centre as a case study
  • Asterisk@Home

If there is anything else that in particular you are interested in or would like me to talk about then let me know.

I’ll also be bringing along various bits of hardware and hope to have a full demonstration running.

At Jeff’s request I will be doing an in depth overview of the difference between FXO and FXS and why it is critically important to any VoIP implementation. This will most likely require at least 20 slides and about 50 minutes of explanation 😛

ThinkingLinux ’06

ThinkingLinux ’06 was held in Melbourne a few days ago. It was organised by Synergy Plus with sponsorship by RedHat. Novel and a few others.

I gave a talk on Open Source in the Data Centre. Luckily this talk was after lunch so I got to do some editing in the morning sessions to tweak it more towards a business rather than technical audience. 🙂

The conference was pretty awesome with interesting talks, ranging from Xen to how wotif.com was started.

Copies of the slides for all the talks should eventually make it onto the conference’s website.

Open Source in the Data Centre

Next Tuesday (17th Oct) I’ll be giving a presentation at Thinking Linux ’06 in Melbourne.

The talk is entitled Open Source in the Data Centre and I’ll be covering things like

  • Load Balancing “Stuff” (IPVS, keepalived, heartbeat)
  • Monitoring using Nagios and MRTG/rrdtool
  • Authentication with OpenLDAP anf FreeRADIUS

and a whole lot of other random things I can fit into 40 minutes.

I choose to blame Pia for putting me in a position to give this talk but only because it’s Jeff’s fault and there isn’t a justblamejdub.com 🙂

If anyone wants to catch up on the Monday night down in Melbourne then let me know.

I’ll put slides up after the event.
