IP Unity(R) Announces Significant Success in Latest GMI 2006 Interoperability Event.

MILPITAS, Calif. -- In conjunction with the Global MultiService Forum Interoperability (GMI) event taking place this week at British Telecom, IP Unity announced today that it has participated in the SIP interoperability test at the BT/Vodafone test facilities in England. IP Unity's Mereon([R]) 6000 Media Server and Mereon Unified Messaging application successfully participated in the SIP testing together with MultiService Forum and IMS network elements from multiple participating vendors.

The GMI event is validating MSF Release 3 Implementation Agreements covering

* Roaming services across multiple network types;

* QoS (Session Border Gateway and Bandwidth Manager);

* IP Carrier Interconnect/Interworking; security interoperability;

* 3rd party applications and service brokering;

* Open Media Gateway Control interface relevant to 3GPP BICN architecture; and

* IPv4/6 Interworking.

IP Unity is one of 26 participants, including a number of major carriers, who have come together to test the MSF Release 3 Architecture. The test environments range from a nomadic subscriber in a single domain to full scale testing of value added services and roaming over multiple domains, including both MSF R3 and 'pure IMS' networks.

Host sites at BT/Vodafone, KT/ETRI, NTT, Verizon and UNH-IOL provide facilities for participating companies to install, test and monitor product performance. In the case of BT's Adastral Park Laboratories in the UK, 40 to 50 test engineers are on-site from 16 companies. Test engineers at the various sites.

"IP Unity has been a strong member of the MSF with submission of technical standards and analysis for our customers and partners. We are committed to the development of interoperable standards, and GMI 2006 demonstrates that we really can deliver a complete solution delivering enhanced services for both MSF and IMS environments for our 120 customers globally", said Keith Bhatia, Chief Business Officer of IP Unity, "IP Unity has participated in multiple GMI events and will continue to provide technical support as well as innovative solutions to the market for IMS voice, data and video applications.

About GMI 2006

GMI 2006 is the industry's only multinational, distributed, interactive test bed to verify key interoperability aspects of NGN/IMS implementations. It brings together a global network of carriers and vendors to test the interoperability of IMS-based infrastructure components in a real-world setting. Providing a test-bed for the full spectrum of hardware, processes and services needed to assemble an effective next-generation delivery platform, GMI 2006 amounts to a massive 'real network' trial of the MSF IMS (IP Multimedia System)-compatible Release 3 architecture announced by the MSF on September 12th. The test program embraces such topics as roaming across multiple network types (including cellular and WiFi), QoS issues (including session border control and bandwidth management), and interoperability with 3GPP release 4 in real-world deployment scenarios that explicitly include first-generation VoIP SoftSwitches, PSTN interworking and evolution to a true IMS network.
