AT&T, BT, and Tata Communications completed the industry's first multipoint, intercompany Cisco TelePresence meeting across multiple carrier networks. AT&T, BT and Tata, together with Cisco, demonstrated the technical ability for a Cisco TelePresence user to call others on any carrier network with high levels of security and reliability. 
The demonstration, which occurred at the Cisco Live 2009 event, connected the following sites on AT&T, BT, and Tata Communication's networks:
- AT&T Telepresence Solution sites in Bedminster and Morristown, N.J., and Chicago, Ill.
- A BT site in Colorado Springs, Colorado
- A Cisco site at Cisco Live in San Francisco
- Tata sites in Boston and London
Cisco noted that more than 350 organizations to date have selected Cisco TelePresence for more than 2,300 rooms. Cisco has also installed more than 500 Cisco TelePresence rooms on its own internal network.
"Inter-carrier connectivity is the next step in building out telepresence for improved collaboration for businesses throughout the world. With the AT&T Telepresence Solution we are providing companies today with the ability to interact with customers or other key businesses in a highly-secure environment. Looking to the future, AT&T is committed to working with other network service providers to bring this proof of concept to market as soon as possible," stated Bill Archer, chief marketing officer, AT&T Business Solutions.
