NTT Communications Expands Corporate Dial-in Function for Low-cost Global Calls

TOKYO, JAPAN – NTT Communications Corporation (NTT Com) announced today that its Arcstar™ SIP Trunking Service has added dial-in functionality in nine markets — Hong Kong, Singapore, Australia, New Zealand, Austria, Luxemburg, Norway, Sweden and Switzerland — which already offer external dialing.

The Arcstar™ SIP Trunking Service, now available in 111 countries and regions, provides low-rate international calls via the Arcstar™ Universal One VPN service. The monthly cost of international dialing from and to global offices and partners can be cut by approximately 70%* with the service. Newly added dial-in functionality can sharply reduce maintenance costs and workload by incorporating existing telephone lines into VPN.

The SIP Trunking Service also helps to streamline operations and raise productivity when used in combination with Arcstar™ UcaaS, which offers communication services such as PBX, conferencing and messaging.

Users pay construction costs, basic and dial-in number fees and charges for calls and the required Universal One port, connection and router. Terms and conditions may vary by country, so please contact any NTT Com office for details.

*Assumes 26 calls per hour, 5 minutes per call and 20 business days in a Singapore office, dialing to/from China, India, Indonesia, Malaysia and Thailand
