AT&T has suspended the CallVantage service. Their web page states the following: Thank you for your interest in AT&T CallVantage® service. Currently we are not accepting new orders for AT&T CallVantage service. We will continue to evaluate our AT&T CallVantage service and remain committed to providing leading, next generation voice services for today's consumer and business customers.

AT&T's CallVantage plan includes unlimited calling anywhere in the United States, Canada and Puerto Rico. Standard and enhanced calling features include Voicemail, Caller ID, 3-way Calling, Speed Dial, Call Waiting, Call Forwarding, Call Return (*69) and Address Book (call logs and call lists), for $24.99 a month.

Additional features include Enhanced 911 and Conference Calling. Directory Assistance costs $.99 per call. At an additional cost you can add AT&T’s softphone service, virtual numbers and fax support.

CallVantage includes a free telephone adapter for the length of your service; however, you pay shipping and handling. AT&T charges a $29.99 activation fee and a $29.99 disconnect fee if you cancel your CallVantage service within one year of signing up.

Additional CallVantage plans include unlimited local calling for $19.99 a month and $.4 per minute long distance. For $49.99 you get a second line and unlimited calling to the U.S., Canada and Puerto Rico.

AT&T's website provides online help, FAQs, email support and telephone support. Customer support responded to our email less than 24 hours and answered all our questions.

Although AT&T CallVantage offers a complete service at a competitive price from a company we’ve come to know and trust, the #1 service, Vonage , offers more features and better calling area at a slightly cheaper price.
