3CX Phone System

Back in the day, when I first started with VOIP, I really wanted to go with some form of asterisk like Trixbox or Elastix but after months and months of trying, I just couldn’t get it stable enough for companies to be able to rely on. Then a buddy of mine suggested that I look at a system called 3CX. At that time they were just on version 10 and it only ran on Windows but I tried it out anyway and it seemed pretty stable so we went ahead and bought a license for it (I believe it was $1,200 at that time).

Fast forward to today, about a month ago I had to rebuild a phone server for a non-profit in Bakersfield. Beforehand, I did a bit of research and found that 3CX was not only now on version 15, but they now supported Linux as a platform! Moreover, since this non-profit only had a handful of employees, I could get them on the free tier! Some of the more advanced features aren’t included in the free tier such as the fax server and it limits the number of simultaneous calls to eight but for this particular project, it was perfect!

Within an afternoon, I had wiped one of their old servers, installed Debian 9.0 on it, installed 3cx on it and was provisioning phones. I built it on a Friday but waited until the weekend to change over their SIP trunk provider (Nexvortex) just in case something went wrong.

That following Monday morning, I made sure to wake up extra early and clung to my phone all day knowing that there had to be something that was overlooked or left un-configured. 8:00? Nothing. 12:00? Nothing. 3:00? Nothing. I finally sent the director a text and asked how the phones were today? She just said, “Good, no problems.” Trust me, that’s a miracle!

It’s been up and running solid for a good month and a half except for one issue: if you’re running 3CX on a server with two NICs, be sure to only have one interface hooked to the network.

For the past few years, I had been using RingCentral for most of clients just because it was pretty much friction free but I’m thinking that for now on, I’ll use 3CX on top of Debian.

iPads and Chromebooks: A Glimpse into the future of Small Business IT

IMG_0004.jpg

I remember the day that Steve Jobs unveiled the iPad. I remember watching the keynote saying that this is going to change things, just like the iPhone changed the mobile phone industry. I bought one right out the gate. In fact, I think that year I bought my dad one as well as both of my siblings. However, I found myself “looking for a reason to use it” and eventually just put it into a drawer and forgotten about it. Throughout the years, I kept trying to fall in love with it, but every time I'd buy a new one, I'd end up not using it again and giving it away. I kept saying, I don't use it because whether at home or at work I'd be less than ten feet away from a desktop so the need wasn't there.

Seven years later, late last year, I decided to try again and purchased a 9.7” iPad Pro. I was doubtful that I'd actually use it other than when I was sitting on the couch watching TV. I was pleasantly surprised. The reverse had happened. Instead of not using the iPad in favor of my computers, I was using the iPad instead of my computers. In fact, at home for all of this year, that 9.7” iPad Pro, now a 10.5” iPad Pro is the device that I'm on from the time that I wake up until the time that I go to bed. I even hardly touch my iPhone while I'm at home since everything also goes to my iPad.

I think there are several reasons for this but if I had to narrow it down to two: it's the maturity of professional, desktop class apps and the fact that the cloud has become more prevalent in our lives, allowing us to access our data from whichever device we have in front of us.

Here's the thing though, if you put my use case aside. I see the trend of iPad-like devices on the rise in the consumer technology market. In addition to Apple with their iPads, Google has their Chromebooks and now earlier this year, Microsoft came out with their Windows 10 S laptops. Despite these three giants having their own approaches to their own versions of next generation devices, I see a lot more in common with the three than you might think.

All three of these platforms restrict what you can install on them. In the case of iOS, you can only install apps from the App Store, in the case of Windows 10 S, the Windows Store and the Chromebooks you can't install anything, you just have the Chrome browser. These restrictions make it almost impossible to install anything malicious on the devices. On top of that, they all update automatically and aside from Windows 10 S, Chromebooks and iOS backup automatically to the cloud. Can you see the trend, yet? The three biggest tech giants in the industry are creating manage-less devices. What happens when you physically break or lose one of these devices? You go and buy a new device, enter your login credentials, everything restores from the backup and you're back to square one.

The reason that I'm so fascinated with these new era of devices is because I can see them impacting small businesses in a large way. Think about this, say a small business with 5-10 employees, instead of buying their employees traditional desktop computers, they bought them one of these devices instead with an LTE connection? And if you add to that a cloud based phone system such as Grasshopper or RingCentral, you would eliminate the need for an office network all together. No more ISPs, routers, firewalls, servers, switches, etc. Plus, since these devices are secure by default, you have a lot less reliance on IT people.

I'm the first one to admit that all the pieces aren't quite in place yet. For instance, there will still be a need for printers and copiers to have some type of network connection. And the wireless providers need to be a lot less restrictive on data caps and data throttling. I do see the pieces falling into place sooner rather than later. If you look at the typical small business productivity software such as Office, Quickbooks, communication and file sharing and collaboration, all the biggest software providers have cloud and/or app equivalents of their products.

Something to think about.

Disk Imaging

IMG_0003.jpg

I'm beginning to feel old here but I remember my first IT job at my high school. At that time, Windows XP had just came out and all the computers on campus were running Windows ME. My first year working there, we spent the whole winter break manually formatting the existing computer lab computers, installing Windows XP, installing all of the Windows Updates, installing Microsoft Office, Adobe Reader, Flash, installing all of the network printers, etc. Over and over and over, again all by hand (I still have that damned Windows XP product key memorized). This was before I discovered imaging. Fast forward 15 years, I very rarely ever rebuild a system from scratch because I developed a new habit. Whether it be for my personal computers or computers for clients, I get the system setup perfectly the first time, create an image for that system and store it. This way, if that computer ever crashes or it becomes time for a client to buy new systems, I just pop start the image restore, come back half an hour to an hour later and vola! A perfect, clean system already configured.

When I started working at California State University, Bakersfield I started in the “installs” department. Our job was whenever departments would order new computers, we were tasked with getting them configured with the necessary software both for the departments standards as well as the campus standards. At that time, we used Symantec’s Ghost to create an image for each particular model of a system that the campus would buy so when we would get that model again, we would already have an image for it. However, by the time my tenure of working there completed, we had signed a contract with Dell where every six months or so, we would send a master image off to them and Dell would do the imaging for us prior to shipping. Because the campus was constantly buying new computers, we could do that.

For small businesses, however, they only upgrade their hardware once every few years, if that. So I highly recommend that when you do purchase new computers for your small business, create an image and try your best to have everybody on the same model and vendor of computer (even though there are utilities to create universal images to be able to create and restore images to and from different hardware).

My go to imaging software for both personal practice and for my IT clients has always been Acronis True Image because of its simplicity and price, it starts at just $50.

So, start using imaging! Your future self will thank you!
