Commencement of Sales of Media Server "NEXIPT MS-IP" with Carrier-Grade Video Conferencing Function
From November1, 2002, NTT COMWARE CORPORATION (Hereinafter NTT COMWARE, Head Office: Minato-ku, Tokyo, President: Yuji Matsuo) will be launching Media Server "NEXIPT MS-IP" which enables communication technology companies to provide services such as multiple-point video conferencing through IP network, automatic voice response (IVR*1), etc.

[Overview of Service Provided by MS-IP]
One of the features of "NEXIPT MS-IP", "Multiple Points Video Conferencing Service", includes "Multiple Participant Display Function" which displays images of all the participants on each participant's terminal and "Speaker Switch Function" which only displays the image of each speaker at a time by automatically recognizing the voice of the speaker. The reservation of conferences can be made on the Web very easily; and when the time of reservation comes, each participant is notified of the conference on his or her own PC. In an emergency, a conference can be started without any reservation. Up to 25 people can attend the conference at the same time.
"IVR Service" provides information on the phone and automatically guides users with pre-defined voice guidance. This service can be used for reception at non-office hours, etc. The users can obtain necessary information by pushing buttons and following the voice instructions. Companies such as communication service providers can easily design voice guidance scenarios and perform design changes depending on the customer needs using GUI based scenario creation tools which are a part of the standard version.
[Features of the Server]
"NEXIPT MS-IP" is a carrier-grade server. It uses hardware that meets the highest level of "NEBS3(*2)" which is used to evaluate the shock resistance of communication devices in U.S.A. and SIP (*3) which is considered to be the standard protocol of carrier service.
[Merit of Installation of the Server]
By utilizing MS-IP, the communication technology companies can provide multiple-point video conferencing and IVR to client companies as added services. Users of the services can use highly value added services without owning the special equipments.
[Sales Target, etc.]
The main sales target of MS-IP are the communication service companies and our sales goal for the coming 2 years is expected to be 1.5 billion yen. NTT COMWARE is forecasting that the integrated services of voice, image, text, etc. will be the mainstay services of the next-generation communication and we are ready to provide various services earlier than any other companies in the IP market which will be increasingly more active.
[The Background of Market Injection of Servers]
With the activation of IP business, soft switch and media gateway technology will be in common use and the fusion between the existing public network and IP network will become more widespread. As a result, communication service companies are shifting their business territory from the existing public network to IP network. As the price per zone is getting cheaper and the extensive zone communication is becoming more widespread, the business need for highly value-added services which combines the multiple channels such as voice, image, text, etc. increases.
[Participation in the Exhibition]
NTT COMWARE is going to participate in the international exhibition, "Fall 2002 VON (Voice on the Net)", which will be held from 7th (Mon) and 10th (Thu) in Atlanta, Georgia, USA. We are going to exhibit "NEXIPT MS-IP" and to introduce "Multiple Point Video Conferencing Service" through demonstration. This exhibition is a major event where the people from all over the world who are involved with VoIP industries gather and it will continue to attract many communication service and other related companies.

[Glossary]
- *1 IVR: Interactive Voice Response (Automatic Voice Response)
- It is a series of exchanges to provide and collect information by pre-recorded voice responses depending on the caller's dial operation or voice.
- *2 NEBS: Network Equipment Building System
- It is the standard used by the communication technology companies when they install equipments. It evaluates not only the tolerance for physical factors such as high temperature, humidity, fire, vibration, etc., but also the tolerance for electrical, electronical and other factors. It is the programming industry standard introduced by Telcordia Technologies, Inc. in USA.
- *3 SIP: Session Initiation Protocol
- It is a call control protocol for IP telephone stipulated by IETF (Internet Engineering Task Force) as RFC2543 in 1999. It is suited for text based message exchange and is Internet friendly.
- *4 IPv4/IPv6
- This protocol is the base of Internet and currently IPv4 is widely used. IPv6 is the next-generation protocol. IPv4 can allow up to 4.3 billion computer connection; however, the concern for IP address shortage is rising with the increase of Internet usage. This is the reason IPv6 became necessary. It can allow IP addresses of up to 38th power of 10.
- *5 SNMP: Simple Network Management Protocol
- This protocol is for exchanging management information on TCP/IP network. IETF standardized it and many products that meet the standard are shipped and thus it has become the set standard.
- *6 G.711
- It is the specification of 64Kbps PCM voice coding technology, which is stipulated as the standard following the ITU-TG series advice.
- G.723.1
- It is the specification of compression technology used to compress telephone conversation or audio signals utilizing very low-speed bit rate. There are 2 kinds of voice compression bit rates: 5.3Kbps and 6.3Kbps; and they are used mainly for VolP, TV conferencing, etc. It has become the standard following the ITU-T G series advice.
- G.726
- This is the specification of ADPCM coding in 40, 32, 24, 16Kbps. It is mainly used for the telephonic relay network. It has become the standard following the ITU-T G series advice.
- G.729.a
- G.729 adopted CS-ACELP method following the ITU-T G series advice regarding voice coding in 8Kbps. G.729a is a new version that simplifies this process.
