Industry Leaders Advance IP Telephony Standard

3Com, Cisco, GRIC, iPass, and TransNexus Agree to Support the Open Settlement Protocol

ATLANTA, GA. September 2, 1998.

Industry leaders 3Com Corporation, Cisco, GRIC Communications, iPass, and TransNexus have teamed up to promote inter-domain authentication, authorization and accounting standards for IP telephony through the Open Settlement Protocol (OSP).

OSP allows a clearinghouse to provide call routing and authorization between carriers. In addition, OSP provides usage reporting through call detail records. Without OSP, there is no open standard solution to perform these functions.

In addition to the overwhelming support of these industry leaders, OSP has been defined within the European Telecommunications Standards Institute's (ETSI) project TIPHON (Telecommunications and Internet Protocol Harmonization Over Networks), chartered to establish global standards for Internet telephony. ``The industry realizes that ubiquitous interconnection will drive market demand, adoption and growth of IP telephony products and services, and OSP is a critical step in realizing the full potential of IP telephony,'' says Stephen Thomas, ETSI's editor for this standard and chair of the Voice over IP Forum.

Major benefits of OSP include:
