Product Description

Amazon.com Product Description

Amazon.com Product Description AT&T CallVantagesm Service from AT&T is a Voice over Internet Protocol (VoIP) telephone service that utilizes the latest in Internet technology to deliver features that are beyond the means of traditional phone companies. With VoIP, calls are transmitted over the Internet, allowing you to communicate nationwide for a single monthly fee. You pay additional charges only for international calls, which are billed at competitive prices. (AT&T CallVantage Service treats calls to Puerto Rico, the U.S. Virgin Islands, and Canada as domestic calls.) Plus, AT&T's Advanced Quality of Service (QoS) provides high voice quality.

AT&T CallVantage Service offers easy 1-2-3 hardware setup:
1. Plug phone cord and computer cable into adapter.
2. Plug adapter into broadband modem.
3. Log onto Personal Call Manager and open your account.

AT&T CallVantage Service is easy to set up. To establish an account, just follow the instructions on the welcome letter, included in the box. Setting up the hardware is also very simple: just plug the telephone adapter into your existing phone and plug the other end into your cable or DSL modem. All DSL and cable modems with an Ethernet port and at least 90 Kbps upstream and downstream speed are supported, as well as both Windows computers and Macs.

In addition to the standard features you expect from your traditional phone company, like caller ID, call waiting, three-way calling, and call forwarding, AT&T CallVantage Service provides a number of features made possible only by use of Internet Protocol technology. You can have voice mail forwarded to your e-mail inbox as an attachment, and then forward that attachment to relevant third parties. You can take your home area code with you when you travel, so your family or work can reach you without paying long-distance rates. And, with an elaborate variation of call forwarding known as "Locate Me," you can maintain a list of places you'll be visiting; when you're out, AT&T CallVantage Service will ring them in sequence (or all at once) until it finds you.

Accessible either by phone or the Internet, the Phone Feature Manager provides access to a phone directory that can store up to 250 numbers, to call logs (incoming and outgoing for the last 60 days), and to many of your other phone settings. A reverse lookup feature lets you access the name and address information of an incoming caller, while the add-to-Phone Book feature lets you move any number from your call log to your Phone Book with the touch of a single button. A display-and-dial feature lets you easily call any number displayed in either your call log or Phone Book, and you can set up to nine speed dial entries. Taken together, that's a lot for a phone service to do. With all the features that AT&T's CallVantage Service makes possible, you can simplify and organize your communications like never before.

I ordered Callvantage service through the AT&T web site on a Monday and received the unit on Friday via FedEx. As part of my order I asked AT&T to port my current home phone number over to the Callvantage service. The port was completed 5 days after my adaptor was received. Once I received the adaptor I was able to activate the unit and service and make outgoing calls. You have to wait until your number is ported over before you can receive calls, until then you will receive your calls on your existing providers network. This whole process was very smooth.

Once I had the service up and running we noticed that there were some issues with the voice quality. Incoming voice was clear but our outgoing voice was dropping off from time to time and made having a conversation difficult. I called AT&T and they did some testing of my cable line and said everything looked ok. They suggested that it might be my cordless phone. I changed phones but still no luck. I ended up calling my cable provider and they came out and found two issues with my internet setup on their end which would cause dropped packets and lead to voice quality problems. Once they fixed this up we have had very good call quality from our AT&T service.

The lesson learned is that you have to deal with two providers and as usual both providers at first blammed the other provider for the issue.

On the positive side, I love being able to call long distance anytime of the day and not worry about charges or cellular minutes etc. AT&T has some nice features which I'm sure will get better over time. I like the call log and phone book feature as well as the locate me feature where you can have the service ring up to 5 phones to locate you if you are not home.

If you have a reliable high-speed internet connection, this is a must-have service. I've had this for just over two months and have been told several times from people on the other end of the call that the audio quality is clearer than any landline connection. Unlimited calling paired with every imaginable feature makes this a must-have service. The "Locate Me" feature allows you to give out one phone number which will ring up to 5 - yes FIVE - different numbers at once -- for example, your home phone, cellphone, office phone, parent's house, whatever - all at once, and you can accept the call at any one of them by just saying "hello" and then pressing 1 on the phone when the automated voice says "AT&T..." Aside from all the advanced features and so forth, the service is INDESTINGUISHABLE from a regular phone line. You plug in your regular phone, just to the VoIP adapter instead of the regular jack in the wall. The adapter provides a dial tone which sounds exactly like the one provided by your local phone central office. All calling and receiving of calls works EXACTLY like any landline phone, so if you don't tell anyone the phone is actually using a VoIP service, they wouldn't know the difference. Overall you can't beat this deal. There's very little in the way of competition so far, the only notable exception being Vonage who may have slightly lower prices but when you use their service, people KNOW you're on an internet phone. When you use CallVantage, on the other hand, your call is routed via the net directly to a nearby AT&T Central Office that immediately patches you in to the Public Switched Telephone Network. The difference is night and day.Read more ›

As someone who was a cellular-only telephony customer for several years, my primary reasons for obtaining CallVantage was to have 1) a portable land-line and 2) a 212 area code before moving to New York. While both goals were achieved immediately, I was pleasantly surprised with the superior functionality and sound quality.

Given that I work as a consultant in emerging telecommunications, I have been tracking VoIP services for a while. In fact, I was using the [previously] free Dialpad.com service since 1999. While the sound quality of these older VoIP services was generally good, there was a annoying delay that disrupted the flow of a conversations. To its credit, Dialpad has corrected the problem as of 2005.

In short, the quality of CallVantage is excellent. There is no delay, no static, no fading. The service is so robust, one has to wonder if the traditional switched phone service providers (ILEC's) will become extinct faster than analysts have predicted.

Similar to how other online services such as electronic banking that have trumped their traditional counterparts, CallVantage offers a number of features unavailable with traditional ILEC's. In fact, the advanced features are even beyond what the cellular companies offer, which is probably going to spur further advanced features in the mobile market.

The additional features are numerous with varying degrees of utility. The web-based voicemail retrieval is especially nice. Email notification is also helpful, especially when you forward these messages to a Blackberry or mobile phone. There are other capabilities like call logs and, for an additional fee, call filtering.
