LOS ANGELES--(BUSINESS WIRE)--Dec. 14, 1999--Charter Communications, Inc. (Nasdaq: CHTR), and High Speed Access Corp. (HSA) (Nasdaq: HSAC) will collaborate on testing IP telephony, the two companies announced today at a press briefing during the Western Cable Show.

Charter and HSA will be operating ongoing DOCSIS cable modem local phone access tests including IP gateways in its first test market in Georgia, with more markets to follow. HSA will use multiple equipment vendors and perform parallel IP telephony tests to trial the various standard bodies and interoperability issues facing primary-line local access services. During the trials, HSA and Charter will test telephony-enabled cable modems and add Internet access and telephony services to a select number of homes in Georgia.

``Working with HSA on VOIP is a natural extension of our relationship,'' said Steve Schumm, Executive Vice President of Charter Communications, Inc. ``HSA is already bringing high-speed Internet services to thousands of our customers, and we look forward to working together and delivering bundled products and services to Charter customers.''

``Both HSA and Charter are committed to quickly bringing new, competitive broadband products to customers across the country,'' said Dan O'Brien, President and COO of HSA. ``HSA is thrilled to partner with Charter once again on yet another new and exciting product.''

Charter and HSA expect to work together to begin offering new voice services over two-way cable plants in the second half of next year.
