About AT&T CallVantage Service
What Is It?
The technology behind AT&T CallVantage service converts your voice into data so you can place and receive your calls over your high speed Internet, DSL, cable, or fiber connection.
Our standard AT&T CallVantage service plans are perfect when you want to continue using your home phone the same way and might want multiple lines or even home fax capability. If you travel a lot, our AT&T CallVantage Softphone option will suit your on-the-go lifestyle because you can make calls directly through your computer via a headset - no extra equipment required.
How Does It Work?
With AT&T CallVantage service, you'll use your phone the exact same way, but you'll get more from AT&T digital phone service than you ever thought possible. You simply plug your computer, your high speed Internet connection, and your standard household telephone into the Telephone Adapter (provided with service) - it's that easy.
- With the AT&T CallVantage Softphone software, you won't need the Telephone Adapter because you'll be making calls directly through your computer. A headset and microphone is required for the voice service.
What Do I Get?
Both AT&T digital phone services let you choose from plans that include local, long distance, and nationwide calling, your favorite features like Voice Mail, Call Forwarding, Call Waiting, and Caller ID with Name, and powerful features, such as:
- Locate Me
- Do Not Disturb
- Safe Forward Number
- Control by Phone
- Additionally, with AT&T CallVantage you can specifically get home fax capability, and with AT&T CallVantage Softphone you can make and receive video phone calls. A PC web camera is required for video calling.

If you have a high speed Internet, DSL, cable, or fiber connection, want to save on calls from home, and would like more control and convenience over your calling, then either of our AT&T CallVantage services is a great choice for you.
