3Com, Cisco, GRIC, iPass, and TransNexus agree to support the Open Settlement Protocol

ATLANTA, GA September 2, 1998 Industry leaders Cisco, 3Com Corporation, 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, 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, ETSIs editor for this standard and chair of the Voice over IP Forum.

Major benefits of OSP include:

  • Confidentiality of all information through Secure Sockets Layer (SSL) encryption

  • Secure, mutual authentication of communicating parties

  • Non-repudiation of all communications through digital signature technology

  • Supports operation through existing firewalls

  • Flexible and feature rich information exchange via eXtensible Markup Language (XML)
