Verizon frustration

I'm working on my gadget addiction - and this year I've come leaps and bounds in my therapy. Well as long as you don't count the iMate, the iPOD mini and well you get the picture - I'm terminal. Two perspectives have added some depth to my experience as an early adopter; one never believe the hype and two it's all about the interface. A classic example of the former is the infrared keyboard - a classic idea but almost entirely unusable. Which brings me to number two and the crux of this vignette. I have been having some major problems with my business line recently. Several times over the last few years the static has gotten unbearable - said phenomenon being followed up by an unhelpful visit from the telco repairmen. Recently I had a few occasions when I'd pick up my phone and have no dial tone! So after several more visits from Verizon and still having intermittent trouble I decided that just perhaps I should try this new fangled VOIP technology. Like I needed an excuse. (BTW Verizon does deserve props for their request repair web site for logging new support tickets. You can request a new repair and part of the process involves an online line test while you wait. The scheduling of the repair visit is also very slick.)

The VOIP glimmer of hope

Now I knew absolutely zip about VOIP until out of desperation I decided I needed to do something about the quality of my line. However I've also lost all patience with new tech solutions that are cumbersome. I want something that is easy to use - that I don't need to spend a connection mangler amount of time fiddling with it to make it work as advertised. This perspective is exactly why I got an iPOD earlier this year. I've been one of the faithful few using my Pocket PC to listen to audio books - the user interface just sucks. Spend half an hour with an iPOD and iTunes and you will be converted. Anyway I digress. The VOIP option dawned on me watching a G4TechTV segment where Leo picks up a Vonage adapter at Best Buy. I also recall Bill Ryan mentioning a VOIP service that he was impressed with. So without further ado I bounded off to my local Best Buy and $79.99 later (before the $50 mail in rebate) I was VOIP equipped. What the heck does this mean you ask? Well I now have a digital phone adapter (made by Motorola) which plugs into the ethernet cable exiting from my cable modem. I plug a phone line into the back of that and viola - dial tone.

 

Signup

Once you've got the VOIP kit you need to sign up on the web with Vonage. The Best Buy receipt actually has a brief 5 step instruction reference - it basically consists of signing up at the Vonage web site and entering your MAC address. I'm not a Best Buy fan - I struggled to find the Vonage kits in their store since no-one knew what I was talking about - but this information is a neat touch. At sign up time on the Vonage site you need to choose the plan you want. At this stage I still knew next to nothing about VOIP other than it was a phone service that ran over my broadband connection. You may want to do some more homework than I did - check out the product tour on the Vonage site. In essence I get unlimited calling in the US and Canada and some really attractive international rates. Apparently these international rates do change every now and then - just be aware of this. In addition it bears mentioning that since your phone service is dependent on your cable or DSL access - when that's down you're SOL. No phone service (but you've probably got a cell for backup).

Number Portability - move your current number

Another big draw for me was number portability. The Vonage web site allows you to type in your current number to see whether it "qualifies" - if it does you can then transfer this to Vonage. You will need to download a Letter Of Authority (LOA) and fax this and your most current phone bill to Vonage to kick-start the transfer. It can take up to 20 business days and some people have had issues making this a reality.

Note on 911 Dialing

911 calls do not work by default on Vonage. This is lifted straight from the Vonage web site but it is important so take heed:

How is this different from dialing 911 on a regular land line?

Vonage routes your call to the Public Service Answering Point (PSAP) providing emergency services in your area. The appropriate PSAP is determined by the physical address you supplied. Therefore, if we do not have the correct address your call cannot be routed to the corresponding PSAP for your area. Another difference between Vonage's Dialing 911 service and traditional 911 services is that the Vonage call will be routed to PSAP's general access line, which is different from the 911 Emergency Response Center. You will need to state the nature of your emergency promptly and clearly, including your location and telephone number, as PSAP personnel will not have this information at hand

If you have kids and are using this as your primary home line then it is essential to understand this - your baby-sitter could be the one dialing 911. Equally important if you're married and your wife beats you. Set up 911 Dialing.

Setup

So at this point I've signed up for service and have yet to install the adapter yet. The included instructions are straight forward. Essentially they tell you to put the adapter in front of your router and behind the cable modem. This configuration means that the router sits behind the phone adapter which has a built in DHCP server and hands out an IP address for your router to use. This works well, especially since the phone adapter can prioritize traffic through the cable modem and enforce what is known as QOS (Quality of Service) of the voice traffic. In essence voice traffic can be prioritized over any other internet traffic that may interfere with your call quality. So if you're on your broadband phone and you start a large file transfer your call quality will not suffer. But - here's the rub - you lose most if not all of your router's capabilities. For example if you use dynamic DNS (like TZO) or some of the more advanced port forwarding features. Granted you could almost use the phone adapter instead of your trusty old router since it supports DHCP and NAT. However I don't want to give up my router with built in wireless and comfort blanket. So I installed the phone adapter behind the router. With the latest routers you should be fine doing this without having to add any custom port forwarding. The adapter should just pick up an IP address and fire up. In practice that didn't happen for me and I had to access the phone adapter's config via a web browser and set up a static address. The downside of having the phone adapter on the internal network is that it can no longer enforce the same QOS as when it was the main routing conduit. You may find then that heavy usage of your internet connection will affect call quality - I haven't experienced that yet but it is still early days. If you do have this problem and you have a Linksys WRT54G router look for the sveasoft third party firmware update. This is supposed to allow you to enforce QOS depending upon the physical ethernet connection. Luckily the WRT54G router I bought at the beginning of the year seems to be one of the preferred routers to use with VOIP.

The pic below shows the 5 connections on the back of the adapter. Two phone line jacks, a power input and then a WAN and PC connection. With the phone adapter in front of the router you plug the cable modem ethernet cable into the WAN port and then the PC port is plugged into your router. The PC port supports DHCP. As you can see here I just have the WAN port plugged into the Linksys under the phone adapter. Luckily this mess is in my wife's office downstairs so I don't need to look at it each day.

The most amazing thing about this whole arrangement is that I could theoretically travel to anywhere in the world - plug my phone adapter into a broadband connection and have my same US number! That is really something. Please drop me an if you have done this.

Call Quality

Call quality is surprisingly good, admittedly I was a little on the wary side so perhaps this skewed my perspective. It's not absolutely 100% clear and every now and then I hear a few clicks but on the whole I'm very happy with it - it just works. I have been dropped a few times on international calls - but for less than 10c/min international I can live with that. It's a lot better than cheap international calling cards.

Conclusion

If you make a lot of US calls, move around a lot and want to keep the same business line or the international rates appeal to you I would say go for it. Spend some time looking at what people have to say - I looked at the VOIP forum at DSL reports -after I bought the adapter ;) - as well as the Vonage Forum and the Vonage web site. There are also a bunch of other features that I haven't mentioned that really distinguish VOIP from the plain old telephone system; things like virtual numbers and toll free 800 numbers, additional fax lines etc. You can also join an affiliate program which allows you to offer one free month to people that sign up through you - if you are interested drop me an with the email address you want me to send the invite to.
