InfoWorld: AOL blocks AT&T instant messagingDec 09, 1999, 16:46 (4 Talkback[s])
"America Online apparently doesn't want to be buddies with AT&T WorldNet. The Dulles, Va., ISP is blocking instant messaging traffic between users of its popular Instant Messenger software and the latest version of AT&T's I M Here Service, which was launched Wednesday."
"The flap between AOL and AT&T could be a step backward for instant messaging standardization efforts, according to industry observers who say interoperability is required for corporations to adopt the application on a widespread basis...."
"We used the protocols and source code that was published on AOL's Web site," said Beth Nagengast, instant messaging product manager at Tribal Voice. "We looked at the documentation on the Web site, and we believe we are in full compliance. We tried to contact AOL [about our product plans], but they did not return any of our phone calls or e-mails."
