8x8 Announces Broadband IP Telephony Interoperability with Netspeak and Motorola; Support for Simple Gateway Control Protocol and Emerging CableLabs PacketCable Initiative.

ANAHEIM, Calif.--(BUSINESS WIRE)--Dec. 2, 1998--8x8, Inc. (Nasdaq:EGHT), NetSpeak(R) Corporation (Nasdaq:NSPK) and Motorola, Inc. (NYSE:MOT) announced the interoperability of their Broadband Internet Telephony technologies.

These technologies are based upon a new protocol designed to bridge circuit-based public switched telephone networks (PSTN) and Internet Protocol (IP) based networks. This specification, called Simple Gateway Control Protocol (SGCP), is a component of the emerging PacketCable Interface Specification being defined by CableLabs. SGCP is also a core component of the recently announced Media Gateway Control Protocol (MGCP).

The technologies being demonstrated together at this week's California Cable Television Association's Western Cable Show are 8x8's Packet Gateway, Motorola's MTA-1, and NetSpeak's Call Agent. Phone calls can be placed between the 8x8 and Motorola gateways using standard touch-tone telephones with the NetSpeak Call Agent routing the call across a broadband cable network. The three companies worked together to ensure interoperability and toll-quality audio. The 8x8 and Motorola gateways compress the audio down to 6.3kbps allowing for the most efficient use of bandwidth without any sacrifice of quality.

8x8, NetSpeak and Motorola have participated in the cooperative PacketCable effort to help CableLabs, its member companies and other vendors draft a specification for interoperable interface requirements. Products meeting these requirements would allow cable operators to use Internet Protocol (IP) technology to deliver telephone calls, video conferencing, and other advanced packet voice and video services over two-way cable networks.

"8x8 is pleased to have the opportunity to work with leading companies such as Motorola and NetSpeak to prove out the promise of Broadband Internet Telephony," said Mike Noonen, 8x8 vice president of business development. "We look forward to working with both companies to enable interoperable technologies and exciting services for cable operators entering the telephony market."

"Motorola is pleased to develop Internet telephony technologies that are interoperable with other PacketCable participants such as 8x8 and NetSpeak," said Robert Molnar, Motorola corporate vice president.

"Multi-vendor interoperability is crucial to the success of IP telephony," said Keith Kelly, NetSpeak vice president of professional services. "This demonstration is an important milestone in the development of next-generation IP-based telecommunications services for cable providers interested in offering residential services."
