Recently I’ve been playing around with a couple of technologies that I haven’t used in quite a while; ENUM and ISN. First, a little information on what these technologies are about.
ISNs and ITADs First, lets talk about ISN (ITAD Subscriber Number) and ITAD (Internet Telephony Administrative Domain). I think the http://www.freenum.org website does a good job of succinctly describing the problem attempting to be addressed:
“The Freenum/ISN system is 12-digit-keypad (telephone handset) friendly method of providing mapping between users.

Just another quick update on the progress of the 3rd edition of the Asterisk book. It’s been a bit slow coming, but Jim and I have renewed vigor and vigilance to be productive and get things done. Since the last update, there was a period of time where nothing got done unfortunately. We did get a lot done in the week off I took to focus on the book (I think we ended up writing about 2-3 new chapters, and updated a lot of the old ones), but then of course work got in the way.

I will admit that I’m not the best at grammar (heck, I still have to make sure I type grammar instead of grammer, but that’s just a spelling issue :)), and other times, there is just some stuff that happens when I get typing fast and I’m on autopilot, thinking too far ahead of where I’m actually at in terms of typing. It gets even worse when I’m writing with good ol’ pen and paper!

I was interviewed at the Wind Mobile launch a couple of months ago, and was interviewed by an online publication. I didn’t remember which online publication it was, so had forgotten all about it until I noticed someone had posted a link to it in the on-asterisk mailing list. Enjoy!

Here is a post I came across from my twitter feed discussing why NDAs are essentially useless and unenforceable in the digital age. Many good points are made, and for the most part I agree with them. I’m not quite so vehemently opposed to them as the author is as I know they aren’t enforceable. The reason I sign them is a good faith gesture to my clients. I think we both know they aren’t useful, but it gives the client a nice litmus test to determine whether I’m just looking to steal ideas, or at least to say, “Hey, it’d be great if you didn’t twitter or blog about anything you learn while looking at our system.

Jim and I have been working feverishly for the past few days, and the only thing that can cure it is more cowbell! Or probably more accurately, more writing!
We’ve been making some good progress on rewriting a couple of chapters so far, and tweaking a few other ones. We’re in the process of finishing up the first drafts of the new installation chapter and the initial configuration chapter, and I’ve started work on a chapter about queues.

I have a client who I need to connect to via a Cisco VPN, and since I use Ubuntu as my primary OS on my MacBook Pro, I’ve often needed to find some information about how to get the client working.
I had previously found some information about patching on Ubuntu 9.04 and it worked great, but since updating to 9.10 I had the same compile time issues I had before, which makes sense since the kernel is different now.

As many of you know, I’m a co-author of Asterisk: The Future of Telephony. While my girlfriend is away in Mexico for a week with the girls, I’m going to try and focus a bunch of attention on getting A:TFoT 3rd edition started (which is much overdue).
If you have any ideas for topics you would like covered in the new edition, or something that wasn’t covered as heavily as you wanted in the 1st and 2nd editions, feel free to let me know, and your ideas will be considered!

In case you missed it, Suzanne Bowen of DIDX recently interviewed co-author of Asterisk: The Future of Telephony and good friend of mine, Jim van Meggelen. If you’ve never had a chance to see Jim speak at a conference, do yourself a favour and try to attend one of his sessions. He is extremely entertaining and informative, and is always a joy to speak to.
Jim also talks about the much anticipated 3rd edition of Asterisk: The Future of Telephony.

For those who missed it, you’re able to get a PDF of my AstriCon 2009 presentation from the http://www.astricon.net website.

There are additional presentations available from the conference as well. Check them out here: http://www.astricon.net/2009/astricon/agendaAtaGlance.aspx
Overall, the conference was extremely well attended and I had a great time. I’ve been to a lot of conferences, and AstriCon is definitely a premiere conference that is professionally run, and contains a great deal of useful information by well versed presenters with little fluff (i.
