More than 500 software and equipment makers have descended on Chicago this week for the Telecommunications Association's GlobalComm trade show. Many products at the show have focused on helping phone companies deliver IPTV services and implement new IP Multimedia Subsystem or IMS standards, which will make adding new services easier and less expensive.
AT&T, the largest phone company in the United States, has a booth at GlobalComm where it's displaying a number of services for large business customers. The company is also preparing for a wider commercial launch of its IPTV service. It's been testing the service in San Antonio for several months, and it expects to deploy the service to more cities in Texas later this summer, with deployments in about 15 to 20 cities by the end of 2006.
