Ooma VoIP Phone System Review

Ooma Core VoIP Phone SystemThere have been many technologies I’ve been skeptical of, none more so than Ooma, a VoIP phone service. If you don’t know what that means, essentially it is a way to make phone calls through your pre-existing internet connection as opposed to using a normal phone line. Ooma has several big selling points, all of them true.

  • You don’t need a running computer to use it.
  • You can hook up all your old normal phones to it.
  • Landline call quality.
  • Free US long distance. International calling available for pennies per minute.
  • Typical services like Caller-ID, call-waiting and voicemail are included.
  • And last but not least, the service is free.  There is also $100/year premier service that adds even more features like an extra phone line, extra phone number and the ability to check your voicemail online.

So what’s the catch?  Well, there are a few.

Purchase Hardware

You do have to purchase the Ooma Core VoIP Phone System.  That link goes to amazon which is the cheapest place to buy it from.  List price is $249.99 but amazon usually has it for much cheaper.

Installation

Because Ooma is an internet service, it isn’t for everyone.  You need to have at least some basic understanding of computer technology.  If you don’t know what an ethernet cable or router are, this product isn’t for you.

The first step is to actually activate your Ooma service which you can do through ooma.com.  It is a very short and simple process where you enter a few numbers on the bottom of the Ooma Hub and then select your primary phone number and password.  After that, you’re ready to install the devices.  You also have the option to port over your current home phone number but that costs $40 and takes more time.

When you purchase the Ooma Core VoIP System, you receive an Ooma Hub and an Ooma Scout.  The hub is what connects into your network like a computer and is what does all the work.  The scout is hooked up anywhere you want additional phone lines.  1 scout is included but you can purchase extra scouts as you need them.  If you have a cordless base station phone with extra handsets, that is ideal because only the base station needs to be near the hub or scout.  I highly recommend the Panasonic Dect 6.0 – 3 Handset System.

Ooma Hub backOoma recommends you install the Ooma Hub between your router and DSL/Cable Modem but I do not because it adds unnecessary complication to your network.  Instead, treat the hub like you would any computer and plug its “modem” port directly into your network router/switch.  As a result, ignore the “home” port.  You can plug a phone into the “phone” port and the “wall” port should plug into your home phone line system.  That is how the Ooma Scout communicates with the Ooma Hub, over your pre-existing phone wiring.  At at any phone jack, plug in the Ooma Scout which just has a “wall” and “phone” connection to hook up another phone.

Packet Prioritization

One reason Ooma wants to hook up right after your DSL/Cable Modem is because it can then prioritize the Ooma packets to be high priority.  Without that, heavy internet usage could cause your voice quality to degrade.  Instead, you can setup Quality of Service (QoS) in most modern routers.  In Linksys routers for example, look under “Applications & Gaming” and then “QoS”.  You will want to add “High” priority to the MAC address of your Ooma Hub.  The MAC address is located on the bottom of the hub.   As long as you’ve done QoS for the Ooma Hub or installed the hub in front of your router, your packet prioritization should work perfectly.

Quality of Service

Call Quality

I was most skeptical about the claimed landline call quality.  I’ve used many other VoIP services, the most popular of which is Skype.  Skype call quality does not compare to a landline in my opinion.  It is acceptable but not awesome.  Vonage is considered to be high quality but is very expensive for VoIP.  Ooma is free after you purchase the initial hardware.  The resultant call quality really did shock me.  It sounds terrific but you don’t have to believe me.  Check out all of these Amazon Reviews.

While I had great call quality, it doesn’t mean you will.  Because Ooma goes through your internet connection, the call quality is completely dependent on the quality of your internet.  Typically the upload speed is what is the biggest bottleneck.  Ooma recommends you have at least 256Kbps.  I have a 768Kbps plan and get about 670Kbps on average.  It appears Ooma tends to use about 100Kbps so it makes sense they recommend more so you have room to make calls while still using your internet for other things.

I attempted to see if I could push my internet connection to its limits and see how Ooma would react.  I did 2 Ooma voice calls (via the premier plan’s 2nd line), 1 iChat video, while also downloading an HD movie and uploading large files to servers.  Ooma call quality did not degrade at all.  In part, this is because the Ooma data packets were higher priority than all the others.  So you can push your internet usage as much as you can and the Ooma calls should not degrade.

Faxing over VoIP is notoriously difficult due the way the compression virtually destroys the fax data stream.  Impressively, faxing over Ooma does seem to work.  They don’t guarantee it will work but it did work in my tests. You have to dial *99 from your fax machine before the number.  It is unclear exactly what this *99 does but I assume it tells Ooma to prepare for a fax and it can then optimize for that.  They imply that the shorter the number of pages are you sending, the better your chances of success.

Blacklists

One really neat feature I feel I have to mention is the blacklists.  This is only a premier feature but it is really cool.  Lets say you get a call from a telemarketer.  Feel free to hang up on them or taunt them as you wish but afterwards, login to ooma.com and blacklist that number.  You don’t even have to enter it, you just select it from your call history.  Then that number can never call you again.  Instead, they will hear a very pleasant voice telling them they are blocked.  In addition to the personal blacklist you can maintain, there is also a community blacklist.  If enough other Ooma users mark a number as blacklisted, then it will eventually be blocked for everyone using the community blacklist even if they’ve never called you.  This is actually how spam blockers work so I consider it a phone spam blocker.  The last remaining unwanted call I get is from telemarketers who block their number.  You can setup Ooma to not ring if no caller-ID information is available.  In all of these blocking solutions, you have the choice to simply block them or send them directly to voicemail.

The Real Cost

If you used a VoIP service that required your computer to be on 24/7, you’ve got to pay for the high power usage of your computer.  The Ooma Hub uses about 10 watts so it will add very little to your electric bill.  If you want the premier service that offers some very attractive extra features, it is $12.99/month or $99.99/year.  The initial hardware purchase is over $200 but hopefully the hardware will lasts for years.  It is essentially like a router and routers usually last for years.  If your hub broke, you’d have to contact Ooma to get it replaced and that cost is unclear.  For me, having the hub and the scout was all I need but some people might need additional Ooma Scouts and those are not that cheap at $69.99 each.  There is no charge for the normal Ooma service plan.  They do technically have a 3,000 minutes/month limit but claim they have never actually shut anyone off due to that.  They say they only have an official limit to prevent commercial use.

The Company

So the calls are great, the service is free, but will this company survive?  That’s perhaps the biggest concern.  Ooma, Inc. is a privately held company so not much is known about their profitability.  The risk is that you buy a $200+ hub that becomes worthless when the company goes under.  On the other hand, the company has shown signs that they may have an ok future.  Currently they only make money off of the hardware sales and premier plan.  They have also said they are looking into business solutions such as an Ooma service with 8 phone lines.  This could be very lucrative for Ooma and allow them to continue to offer their free service indefinitely.

Conclusion

If you are willing to take on the risk of dealing with a company you don’t know much about, the payoff could be big in phone bill savings.  I didn’t believe all the amazon positive reviews but in the end, I have to agree with them.  The service has worked great.  I like some of the extra premier features like the blacklist and extra phone line and phone number.  I have a local phone number but also a number near relatives across the country so that they can call me without paying long distance.  You can’t do that with a real phone line, nor the blacklists.

Ooma is relatively easy to hookup and use.  The extra features and nice website make me highly recommend it.

Cheap WiFi Antenna Boost

We recently setup a wireless antenna and bridge for a customer in Occoquan, Virginia that needed WiFi to be transmitted across a large building and through floors. While the setup worked, the signal was poor. This caused lows speeds and even occasional lost connections. Therefore we setup a cheap directional antenna to point the signal directly where it needed to go. This fixed the problem by increasing the signal strength by about 40%.

How To Build The Antenna

Go to freeantennas.com’s Ez-12 page to download the image at the bottom of the page. Then resize the image as needed, print it, use business-card strength paper, glue on the aluminum foil, and put it together. Patrick Norton explains this simple project on his old DL.tv show.

Mac Software Striping RAID Performance

The Mac OS includes software RAID options.  Using the striping option, you can double your storage and greatly improve your read/write performance.  But what is the true performance gain and is it worth doing?

Mac Pro

What you need

First, you need a Mac capable of holding at least 2 drives.  This is actually a problem for most Macs.  Only the Mac Pro is capable of that off the shelf.  The Mac Mini can be hacked to do so but it involves removing the DVD drive and soldering in a 2nd hard drive.  The system I used in this test is the latest entry-level Mac Pro from early 2009.

Second, you need another hard drive.  The Mac Pro can actually hold 4 but for the purposes of this test, I’m only adding 1. This Mac Pro comes with a 640GB Western Digital Caviar Blue so I purchased another identical to that.  It is best to have 2 identical drives when doing striping so that both drives can be fully used.  If you’re looking for Mac Mini drives, we recommend the 500GB Western Digital Scorpio Blue.

Backup original drive

In order to add the 2nd drive, you’ll need to fully backup your first drive so that you can restore it later.  When creating a RAID setup, the drives will be wiped clean.  If you already have a time machine backup, you can do a restore from that but I prefer using Disk Utility to do a backup and restore because it can create a fully bootable 100% identical backup that you can then restore from Disk Utility off of a Leopard boot disc.  Disk Utility doesn’t word things very well.  Both a backup and a restore are both under the Restore tab.  When you backup, you just do a restore from your Macintosh HD to your external backup drive.  If you want the backup to be bootable, be sure it is partitioned with a GUID Partition Table scheme under Options.

Add the drive

Now that your data is backed up, you can add your new drive.  In the Mac Pro, this is the quickest and easiest hard drive addition ever.  Simply unlatch the drive holders and slide one out.  There are 4 screws already in there waiting to go into the new drive.  Then you just slide in the new drive and that’s it.  If you’re using a Mac Mini, you’ll need to follow this Mac Mini upgrade guide.

Mac RAID

Create the RAID
Boot up the mac off of a Leopard disc by holding down C.  Choose your language and then you’ll be able to launch Disk Utility from the top menu.  Select one of the drives and go to the RAID tab.  Enter the RAID Set Name to be the standard drive name Macintosh HD.  Then drag both of your drives to the RAID set window.  Both will show up and show the combined storage based on your RAID type.  Mirroring is for a duplicate backup.  Striping is for performance and extra storage.  You can select Create to create the software RAID and it shouldn’t take more than a few minutes.

Restore

If you did a time machine backup, you can go through the standard Leopard install and choose restore from time machine.  If you did a disk utility backup, select your new Macintosh HD volume and go to the Restore tab.  Choose your external backup drive as your source and the Macintosh HD as the destination.  If you have a lot of data, this can take several hours.  If all went well, your system should now be able to boot off your new striping RAID Macintosh HD volume.

Performance

Now that we’ve got our striping RAID, how does it perform?  Using the Xbench disk test, the drive performance has gone from a score of 73 to 112.  That’s about a 53% improvement overall.  The test uses a variety of disk usage and this striping will perform differently based on exactly how the data is being used.  The biggest benefit will be for large files.  For example, if you use a virtual machine like VMware Fusion, the virtual RAM is written and read to the hard drive when you do a suspend or resume of the OS.  The result is that with a striping RAID volume, this feels about twice as fast. Striping also combines the drives so you double the capacity.

The down side

The biggest negative is that with 2 drives required to be working, we’ve doubled the likelihood of the Macintosh HD volume failing.  If just 1 drive breaks, the whole volume is lost.  Fortunately, Apple provides time machine which gives us a reliable and effortless backup.  If you do lose a drive, you’ll need to replace the bad drive and restart the RAID set from scratch and restore.  Another downside is that because this is a software RAID, it does use a little CPU which hardware RAID would not.  But a Mac Pro hardware RAID card will set you back $700 and the CPU usage is so small, I can’t even notice it when looking at Activity Monitor.

Conclusion

If you want to massively improve your disk performance, adding a second drive and creating a striping RAID set is a great choice.  This is easy in a Mac Pro but can be done on a Mac Mini with some work.  Just be sure you always have a time machine backup running in case your RAID fails.

Music Studio Basics

Since I started working with music studios 20 years ago, I have seen what would have cost $100,000 with reel-to-reel tape equipment now come down to $10,000 with computers. Even more amazing is that home studios which used to rely on muddy sounding 4-track cassette recorders can now produce inexpensive high-fidelity recordings through a computer.

Music StudioAt Tech DC we have setup several music studios, from small one-mic setups for podcasters to 26 simultaneous channel studios to record entire live bands.

The first question to ask yourself when setting up a studio is Mac or PC. While great software exists for both platforms, the Mac is generally more popular for musicians.

While recordings can be done using a laptop, generally you will want a more powerful system in order to add more channels and effects. Effects like reverb can be very processor intensive. If you don’t have an isolation booth, remember to get a quiet computer so that it’s humming doesn’t leak into your recordings. This is another reason that Macs tend to be popular.

The software that records both audio and MIDI (keystrokes, pressures, pitch, etc.) is typcially referred to as a DAW (Digital Audio Workstation). These include Logic, Cubase, ProTools, Cakewalk, and many others.

Logic & Logic Studio (Mac)

Logic was made by Emagic, then bought by Apple in 2002. It is my current favorite and the Studio version comes with loads of virtual instruments that can be played via MIDI.

Garage Band (Mac)

This is easy to use and included in the iLife suite. It is still very powerful and is built using the same engine as Logic.

Steinberg Cubase Software (PC & Mac)

Cubase is an excellent DAW for PC users.

Keyboard Controllers

Korg, Roland (and Edirol), Yamaha and others make keyboard controllers that can be used to control virtual instruments. Depending on the type of music, this can be very helpful. Virtual instruments come with DAWs and can be added on separately. They vary from unreal synthesizer sounds to professional pianos and organs.

Midi and Audio Ins and Outs

PreSonus of Louisiana makes the Firebox that is inexpensive, small, and perfect for very small studios, assuming that you need no more than a couple of Mic/Guitar inputs at a time. For larger studios, they make the 26 channel FireStudio.

M-Audio is a popular name in Audio/Midi interfaces as well as keyboard controllers. They have a 26 Channel ProFire Audio interface and a smaller 6 in X 10 out Firewire interface.

Mackie has long been the most popular brand for mixers. The mixers can be used to send mixed down audio to a small Audio I/O box like the Firebox. Mackie also sells digital Onyx mixers that send multi-channel audio to a computer.

Mark of the Unicorn is another old name in audio and currently sells the Traveler-mk3 audio interface.

Where to Buy Stuff around DC

There is no one perfect solution for everyone. You need to look at your budget, recording needs, and see what hardware and software you are comfortable using. Check out these stores to see the equipment in person.

Chuck Levin’s Washington Music Center is my favorite local store for instruments and equipment. It has been here since 1958. Other local stores to visit are Guitar Centers in Falls Church, Virginia, Fairfax, Virginia, and Rockville, Maryland (formerly a Venemin’s Music).

LCD Monitors trending towards 16:9 ratio?

Since HD began, widescreen TVs have been 16:9 ratio in screen size. But widescreen computer monitors have always been 16:10 ratio. If you’ve got a 24″ LCD, it is undoubtedly the 16:10 ratio of 1920×1200.  But just over the last few months, a few 16:9 ratio monitors have come out and many think this will start a new trend since computers will be used for HD content more and more.

An example of this new even wider ratio is the Samsung 2343BWX 23″ LCD.  It just came out in February and has a 2048×1152 16:9 resolution.  This has 3 major advantages. The first is that if you play HD video, it can completely fill up the screen since it matches the 16:9 ratio.  The second is that if you cut the screen in half, you’ve got 2 windows of the width 1024.  This happens to be the magic width that most web developers try to build for.  The result is that you could have 2 browser windows side by side on this monitor.  The last advantage is that even though this is 1″ smaller than its 24″ older brother, the 2048×1152 resolution actually has more total screen real estate in pixels than the 1920×1200.  You cut about 4% on the height but add about 6% on the width.  Dell has gotten into this game too with the SP2309W which has essentially the same specs as the Samsung.  At Dell, the monitor is so popular it now has a 3-5 week wait if you order today.
