Last May, we announced AT&T Dynamic Network Applications, or DNA, an integrated portfolio of IP services that will support the next generation of business communications – everything from voice to conferencing to messaging and beyond.
This portfolio of services is standards-based and capable of interoperating with service-oriented business applications from AT&T and third-party providers.
The first service available in the portfolio was AT&T Voice DNA – an IP Centrex service.
We’re proud to say that TMC, the sponsor of this conference, has selected AT&T Voice DNA service as its 2005 VoIP Product of the Year Award winner.
We’d like to thank TMC for this award – and also for the three 2005 VoIP Service Provider Awards presented by TMC’s Internet Telephony magazine late last year for our AT&T CallVantage Service.
One of the key advantages of AT&T Voice DNA is the ability for customers to manage advanced features of the service through our BusinessDirect customer support and network management portal.
On the right of this slide you can see the screens for the control module where customers can assign numbers – and the portal for assigning features and functions.
Customers can make all their line-side changes live on the portal.
The key here is the ease of use and the control.

Easy access from anywhere from Internet
Secure experience including SSL encryption
Reliable, network based solution
Through one interface, users can set up either an audio or Web conference.
On an audio conference, there’s an identical experience for participants using an IP connection or a traditional TDM phone.
Web conferences offer features such as document collaboration, chat, and file sharing.
And because it’s IP-based, a number of services can work together.
So in our AT&T Labs, we’re testing services that integrate features such as speech-to-text and advanced search.
So users can get an automatic transcript of a conference call – then use advanced search to find topics they want to replay, and click to hear the sections of the call they want.
