First use of the Open Settlement Protocol (OSP) for interoperability

Voice On The Net (Booth 219), Las Vegas, April 13, 1999 -- GRIC Communications, Inc., today announced the availability of Open Settlement Protocol (OSP) interoperability with Cisco gateways. OSP allows routing and authorization between multiple service carriers.

GRIC's first implementation of OSP will inter-work with Cisco System's AS5300 and AccessPath VS3 Voice Gateways, and will be available in the summer of 1999. GRIC and Cisco have worked within the ETSI-TIPHON standards organization to develop and promote the standardization of a communications protocol between H.323 equipment platforms and back-end services, such as authorization, route determination, and call detail record (CDR) collection and settlement. Cisco and GRIC are among the co-sponsors of the work-item to define the specifications of OSP version 2.

"OSP compliance is critical for the continued expansion of VoIP services and applications," said John Jacquay, GRIC's president and chief operating officer. "OSP will help open the door for emerging services such as e-commerce and customer care."

With the implementation of the OSP feature, inter-domain call detail records are forwarded to the GRIC settlement system, processed, and then transmitted as settled records to billing system platforms. Systems integration effort is required to provide the interface between the GRIC servers and the billing system. Intra-domain records generated by the Cisco equipment are accessed through any Radius based accounting and billing system.

"Cisco is very committed to working with the standards body to define protocols that enable Cisco's Open Packet Telephony framework," said Alistair Woodman, Group Manager of Packet Voice Technologies at Cisco Systems. "We are encouraged to see multi-vendor implementations of ETSI-TIPHON OSP, and will continue to work with standards-based solution providers such as GRIC to deliver the benefits of OSP to the marketplace."
