Vonage, a company on it's way down
350369
I hope that if you are looking to buy this product that you have considered other VOIP providers.  I was a Vonage customer for over 8 years, and while it had its quirks, it was an ok company, or so I thought.  I recently decided to go with another VOIP provider and had been paying the "slightly lower rate" by paying once a year.  I was not quite 1/2 way through one of those pre-paid years, and cancelled my service and they inform me that they can't refund a prorated amount.  "The system won't allow it".  This is incredibly poor customer service.  At least other companies advertize that they have a yearly contract, they don't bury in small print that if you quit early (after 45 days of payment) they can't refund the remaining amount you paid.  VERY POOR CUSTOMER SERVICE.  With this kind of customer service, they will not be around for long.

It's a great concept, if customer support was responsive.
As of the last two weeks of December, 2001, it is not.
Unable to get through voice-call customer support.
The web site is slow and loops me around endlessly
when I attempt to purchase a subscription.  Too bad.

DON"T BUY IT, SLOW DEATH in less than 3 yrs of use! We took care of the product and noticed it slowly went down hill. First, issues was it began to have a delay in transferring calls over, anywhere from 5-10secs. Eventually out of every 10 calls about 8 of them would have delay issues when call was on the line. Delays eventually turned into failed connections. We paired with other phones (cell, landline,VOIP) and same issue. In the last 3 months the headset started to have crackling/static during the calls. DO NOT BUY! NOT WORTH THE PRICE. Customer support was surprised headset lasted 3 yrs and said that is a 'good life' for the $230 product.

I bought this router on Nov 2013.  I've been happy with it, even recommended it to friends.  Today, I needed to login the website but I could not - the first time it has ever happened.  So I Googled Skydog, and as it turns out it has been bought out by Comcast back in July/Aug.

From the "new" website, it shows there are no plans for selling Skydog anymore, although the 3-yr service will be honored (no doubt executed Comcast-style).  I feel abandoned by the Skydog founders.  I really thought they had a service that really helped out busy parents in an ever complicated world.  What makes it worst, is that my friends found out and bought this router because I recommended it.

My advice is to be wary of kickstarter enterprises.  My mistake was believing that Skydog will be around for the next three years, ever improving their product and services so parents can provide their families the benefits of having internet access and be able to control some of the unsavory aspects of it.

Edit: it seems that obi fixed this issue and I haven't been charged again for annual usage.
This little device was great when I started using it but then when I was trying to conduct business phone calls my phone stopped taking calls and only my computer rang. With no setup to accept calls on my desktop I had no choice but to pay their $10 ransom ware fee. Not a happy customer which is sad since I've recommend these to lots of friends.

The VOiP service has noticeable lag.  That's not the horrible part though.  What makes it terrible is that Ooma won't let you cancel online.  Instead they make you call and spend 20 minutes on hold and arguing that you really do want to cancel the service.

At first I was pleased.

But the call quality is poor,  I get dropped every once in a while and sometimes it claims the number dialed in not in service, (even after I double check and repeat)  Yet my cell phone dials those numbers first time with no issues.

But the worst part is the BS having to call them on the phone jump through hoops to get make any changes that lower your bill.  If you want to upgrade a service you just click and you are done.  If you want to downgrade it is the old Comcast style BS,  calls, waiting, menus and broken promises.

UPDATE.
After cancelling "premium"  level service  Ooma put me back on it a couple of months later.  When challenged they pretended to have no record of my canceling even though it was clearly cancelled and restarted...

They charged me for a few months before I spotted it, and claimed I must have clicked on some offer or other (complete lie).

Ooma  are cheap fraudsters using dirty tricks to pay the bills.  I warned them I would be bringing fraud charges against them if they try this again.

I received the VDV21-VD Vonage modem as a replacement unit about 4 months ago. I started noticing slower Internet connectivity since using it. Two weeks ago, my connection started dropping out and I noticed error messages on the VDV21-VD. it got worse daily. One evening, after getting an error, I picked up the unit and was shocked to discover the base scorchingly hot! As I pulled the modem up to my nose I could smell something burning, or close to it. I immediately disconnected it and connected my incoming Internet cable directly to my router. The connection speed was amazing without the modem attached.
I wrote to Vonage online in hopes of alertng them of this potential fire hazard. (I still wonder what could have happened if I had gone out that night!) Vonage customer service never responded." Then I filed a complaint with their 'Board' online and a rep finally emailed me a form letter message  with a phone number to call. Called him twice this week and only got is voicemail. Apparently t the Vonage Executive Response Team techs don't answer their phones...at least not this guy.
I'm cancelng my Vonage acct over this. I simply refuse to do  business with a company that ignores a serious fire hazard-related issue.  I now have Skype as a back up line. If you buy this modem,' monitor the heat of the casing.
FYI.

The Magicjack 'service' is perhaps the most frustrating replacement service I can recall ever experiencing!  An example of one of those frustrations was, if for any reason the service is dropped (e.g. a blip on the internet) the service is dead until you manually unplug the unit and reinsert.  Thus, if you are out of town, you have no answering machine to capture messages until your return.  Add the all to frequent dropping of calls and inability to complete a connection when people call and you try to answer.  I have just dropped the service after the 1st free 6 months (several startup cost were not free).  My advise:  Stay away from this not ready for prime time service.

Finally got rid of my Vonage line.  I'm paying the same now for 1 year as per month.  The success of this device is totally dependent of the service you select.  So far, so good on Vestalink. Can't tell the difference between ObiHai box and the Vonage box.  If you get the right service, this is a great little device.  Works as advertised.  I had written a very negative, prior review with 1-star because you had to use Google Talk which by that time had run out of phone numbers, making the device pretty worthless...  Now, there's more options, several VoIP services to select.  The set up can configuration can be pretty tricky, so beware if you're non-technical.  The hardware works well when paired with the right service

I found the voice quality worse than other voip providers. Also there the caller id only provides the number not name, and there is no call waiting-id

I purchased the immediate predecessor to this phone in December 2003.  While the reception was outstanding -- that had been an issue with my previous telephone -- the handset stopped working after 9 months and the resulting customer service has been nightmarish.  Here are the specifics:

In August, the microphone on my handset stopped working.  I'd pick up the phone, say hello, and get nothing but dead air.  I'd call the person back (using the magic of caller ID) and they'd tell me that the phone picked up but they couldn't hear anything.  So I called my cell and had one of those ridiculous conversations with myself, one phone to each ear.  Sure enough, the microphone wasn't working.

I then called customer service (on my cell, of course, since the handset wasn't working).  This resulted in what I now look back on as some fairly rote fix attempts.  First, they told me to go out and buy a new battery.  This didn't work (the old battery seemed fine, although I found it interesting that they said the batteries have only a 1 year life span).  Then, they had me use a certain key combination to reset the phone, then wait 12 hours before trying it.  I did this, but the phone still didn't work.

On my third call to customer service, they agreed that it sounded like the phone needed repair, and said I could send the handset into a place in Texas for a refurbished replacement.  The problem is that they insisted I send THE ENTIRE PHONE IN, base unit included.  I explained that the base unit was working fine, and that I could use the speakerphone in the interim.  They said no, that was the policy.  I then asked to speak to a supervisor.

The supervisor was very nice, but said that that was simply their policy -- to send the entire phone in.  I explained that that would mean I'd be without my home phone for what sounds like two weeks, unless I went out and bought another one.  She said, "I'm sorry if that causes you any inconvenience."  Any inconvenience?  To be without a phone for two weeks?  Having to use a speakerphone for two weeks is an inconvenience; being without a phone entirely is nutty.  It's as if the water department said, "I'm sorry, you won't be able to flush the toilet for take a shower for two weeks... hope that doesn't bother you any."

I very calmly asked to escalate this, but she said she was the highest escalation point.  After I expressed some surprise that the CEO of Panasonic would be taking calls like this, she gave me a number in New Jersey.  It turns out the call center, by the way, was in the Philippines.  That explained why she was so nice, and made me feel a little guilty about my sarcastic you-must-be-the-CEO crack.  [But it also illustrated one of the downsides of outsourcing, and it struck me as curious that they don't offer 24 hour support, since that is supposedly one of the advantages of farming out these things to a place that's 15 hours ahead of you.]

The first time I called the New Jersey number, they forwarded me back to the Phillipines.  The second time I called, they gave me a different number, which turned out to be a slightly different phone tree (giving me hope), but sending me back to the Philippines nonetheless.  The third time I called, they put me on hold.  After five minutes of hold (all these calls are off my cell), I started writing this review.  It's now 26 minutes into my hold.  I'll give them another five minutes before giving up.  In the meantime, I thought you should know the kinds of hoops Panasonic makes you jump through to resolve a product defect of their own making.

I have used a NetTalk for a couple of years, and it worked fine, but when I had a problem, the customer service was horrible.  Calling the only phone # on their home page gives a "disconnected" message.  The only way to reach anyone is by chat, and the last time I tried it, I waited 2 hours and the chat system closed down before I got a response.  Go with Magic Jack instead.

I needed a new phone that was 2 Line (for my business), 5.8 Gigahertz (as to not interfere with my wireless computer network), had a corded handset on the base (I'm on the phone all day and need to connect my headset to something that won't run out of juice), and has cordless capability so I'm not always tied to my desk.  This is the only phone that currently seems to meet this criteria.  So, while I'm unhappy with it I'm not sure I can return it.

What really surprises me is the problem the base is having with the miltiple phone lines.  Currently, I have one line from Vonage and one line from SBC.  They both work fine when only one is plugged in, but when the SBC line is plugged in Line 2 and Vonage is plugged in Line 1, the SBC line suddenly starts having caller id and ringing problems.  Motorola tech support keeps passing the buck and saying it my phone lines.  But it seems that others are having similar problems.  So I reall don't appreciate having to deal with the unknoledgeable tech support and being a beta tester of what should be a working product.  There are some other things about the phone I'm not really happy about and would go to another brand, but no one else seems to make this particular type of phone yet and I need it for my business.  I'm just surprised that a company who makes some of the top cellular phone technology combining phones, cameras, computers, pda's, radios, can't get a simple two line corded phone right.  Good-bye Moto!

Researched VoIP services intensively. Most wanted ongoing monthly fees. Rather expensive.
Ooma has a flat initial charge for hardware, and a charge to transfer my number.
Now I only pay the monthly tax, a modest 4 bucks. What a sweet deal!
If only I could block the wretched spammers, I would be in heaven. Sigh...

Bought this device with all the good intensions. Great idea from Trendnet that I had many hope will allow me to make conference calls with Skype without picking us a handset.
The installation was somewhat painful but I've managed to overcome most of the issues by downloading drivers from their WebSite.
The main issue with this device is the voice quality. It is just not usable. There is a major delays , echo and it continuously disconnecting.
My recommendation - don't come close to it!!!
