  1. People are Talking! Internet Voice Gateways Oki Electric Industry Co., Ltd. James Knowles IP Product Manager

  2. Presentation topics: • What is an Internet Voice Gateway and what are the benefits of VoIP? • New products • 3 new products launched at CEBIT 2000 • Pricing • Competitive pricing for FY2000 • New target application • Case study of Internet Telephony Service Provider • Global IVG success stories • OKI IVG success stories that span the globe • Reviews of OKI Internet Voice Gateway • reviews showing OKI IVG solution’s high quality of voice

  3. What is Internet Voice Gateway? • Creates the bridge between the PSTN and a IP Network • Voice is converted, compressed & grouped into data packets PSTN Tokyo Paris BS1200 Gateway BS1200 Gateway IP Network

  4. Why use a packet switched network? Circuit Switched Voice Network • Dedicated capacity of ‘channels’ for duration of • connection • Inefficient use of available capacity • A channel, such as a standard telephone line, has a capacity or bandwidth of 64Kb/s

  5. A Packet Switched Network • Available data transmission capacity now shared for • voice, fax and data • - all are now transmitted as data packets • More efficient utilization of capacity • - Can have just one network for data, fax & voice • - Minimize infrastructure and maintenance costs • - Offers free calls over existing data network

  6. Benefits of an OKI VoIP solution • The OKI VoIP solutions use ‘standalone’ gateways which means easy installation with no disruption to current phone or data network infrastructure • The OKI VoIP solutions offer a structured migration path towards a wholly IP infrastructure for voice and data using OKI’s IP PBX • OKI VoIP solutions offer large cost savings, with payback times typically less than 6 months • OKI VoIP solutions offer the best quality of voice using advanced ‘jitter buffer’ technology • OKI has experience of installing and supporting VoIP networks from the smallest, to those including over 250 sites and global organisations that span the globe!

Nikkei Communication, Dec. 99 - Nine products tested by NTT Communications Test conducted in three areas: 1. Normal Conversation -MOS -Delay Time 2. Random Number Read Accuracy Test -MOS -Number of digits correctly received 3. Comparison of Wave Form -Loss of sine wave form of received signal *MOS score (Mean Opinion Score) is a widely used subjective measure of voice quality) Article #2.
