Vocal'Net & Vocal'Net+

In 1999 Inter-Tel, Inc. announced that a Signaling System No. 7 (SS7) interoperable version of its award-winning Vocal'Net IP telephony gateway software would be released in Japan. Distribution would be through NTT International (NTTI) and NTT Communicationware Corporation. The gateway software interoperates with Nippon Telegraph and Telephone (NTT) switches and SS7 signaling.


SS7 is a signaling protocol used within traditional telephone networks for providing call control between network locations. In Japan, SS7 capability allows caller information to be transported across NTT carrier networks quickly and efficiently. As a result, network features like calling party I.D., call forwarding and call blocking can be implemented transparently over IP with the Vocal'Net gateway.


With the addition of SS7 support, the Vocal'Net gateway can be incorporated transparently into an existing NTT SS7 telephone network. With Vocal'Net, SS7 capability becomes available over an IP network as well as a traditional telephone network. For example, a Vocal'Net gateway can receive call information from an origination SS7 telephone network in Tokyo, transfer it across Inter-Tel's Vocal'Net IP gateway, then deliver it to a destination SS7 telephone network in Osaka. SS7 functionality is generally considered to be critical to the widespread deployment of Voice-over-IP (VoIP) technologies by major carriers such as NTT.


NTT International commercially released over 100 Inter-Tel Vocal'Net IP telephony gateways since April 1999 for Japan.


"This represents yet another milestone in the strong relationship among NTT International, NTT Communicationware and Inter-Tel," said Steven G. Mihaylo, Inter-Tel, Inc. chairman and CEO.


Shuji Arima, NTTI's senior vice president, multimedia systems department said, "We believe that Inter-Tel's Vocal'Net software is the first SS7 Voice-over-IP product in Japan, and SS7 is the essential function for IP telephony from now on. The SS7 interoperability makes the Vocal'Net very attractive to the telecommunications industry, ISPs, and companies with heavy long distance traffic."
