» Got Contract Work?

Gabe and I want to be sure that our start up company, Izeni, has a cash runway that’s long enough to ensure that we can have a proper lift off. To that end we’ve been doing some consulting and contract work (mostly low-hanging fruit) to slow our burn rate, and it’s worked fairly well because we’re in bootstrapping mode and our expenses are relativity low. So, although we’ve never really sought contract work, we do like it; and I thought I’d do a quick post officially soliciting it.

So without further ado, Izeni will be accepting all kinds of technical consulting and contract work. Our specialities are Python coding; website development (particularly using the Django framework); Linux systems administration (Apache, *SQL, Postfix, Mailman, IPtables, Samba, Bash, etc.); and VoIP-based telephony (Asterisk and Freeswitch).

We can also do general computer and network support, online marketing, and a myriad of other technical and business odds and ends.  :)

Izeni is based out of Utah, but we can also telecommute.

Please let me know if you have any contracting and consulting opportunities or know of any companies looking for web guys, programmers, or other technical contractors. Otherwise, feel free to repost this (pass the word along), or just keep us in mind.

» VoIP Routing Loop

The other day my boss and I managed to create a call routing loop between two of our phone systems. It was kinda fun, in one of those painful ways. Here's how it went down.

Phone system A has extensions in the range of 2XXX. Phone system B has extensions in the rage of 1XXX. The PBXes have an IAX2 trunk between them to allow direct dialing. The phones themselves have a dialplan which recognizes 1XXX and 2XXX as patterns, which allows for faster dialing. Users must dial a 9 to reach an outside line.

There was just a slight problem. Due to a misconfiguration on my part, B was set up to route any unknown 1XXX extensions back over to A. For a real extension, say 1000, the rule wouldn't match because B would know to send that call to the local user. But let's say that somebody's boss forgot to dial a 9 when dialing a long distance number. So the phone sees the first 4 digits, 1 + area code, and assumes it's an extension. A sends the call to B. Well, that extension didn't exist so B sent the call back to A. That would be the point when the fun began.

I would have thought that the PBXes would create a whirlwind of calls until the original call eventually timed out and broke the chain, thus bringing all the calls to a halt. But somehow that isn't what happened. The system stabilized at 400 or so active channels. Sat that way for a few hours I believe. What finally did stop it was my removing the rule to allow 1XXX over the IAX2 trunk from B to A. Within just a few seconds all the calls came to a grinding halt (in a good way).

I've decided then that having local extensions that start with a 1 is a less than desirable thing. It's not the end of the world, but avoiding it can relieve some potential headaches so I intend to eschew it where possible.

» Izeni time

Well, if you don’t blog about forming a new company and getting ready to launch a new product, what do you blog about? I guess when you’re busy, that’s what it takes to get you posting again.

I don’t have much to say right now, but we’ve worked our guts out, spent much of our savings and gave a slice of our lives –it’s the American dream. There will be time to talk more about what we are doing; right now, I just need to get some sleep.

Before I do… now’s a good time to give thanks to my wife for putting up with all kinds of nonsense. I love you Emily. Thanks for your support :)

Now head on over to Izeni’s website and sign up for announcements.
