Colt’s VoiceLINE(v) is now available in Japan, its 14th global market and first outside of Europe.

The IP-based ISDN Phone Service enables enterprises to simplify the migration to SIP Trunking. Specifically, VoiceLINE(v) delivers direct ISDN to a customer’s TDM-based PBX alongside enhanced geographic coverage via next generation IP technology, utilising SIP Trunking to be delivered over a variety of IP-based access points.

VoiceLINE(v) will replace Colt’s existing VoiceLINE ISDN, with customers now being able to continue to use their TDM or hybrid IP-TDM PBX.

Masato Hoshino (pictured), Colt Technology Services president and head of Asia, said: “Last year, many companies around the world activated their business continuity plans, triggering dramatic growth in voice traffic. As new work styles were adopted, the demand for voice traffic among call centres, conference service providers and large enterprises continued to grow. We are proud to support our customers with market-leading voice services that can be delivered under any circumstances.

“We are excited to expand our VoiceLINE(v) into Japan, putting us in the best possible position to support our customers’ business objectives in Asia,” Hoshino continued.  

Colt explained that a futureproofed VoIP-based ISDN telephony service – which offers more features than traditional TDM voice – means enterprises can continue using their current PBX and telephone devices without having to invest in their own IP network. This gives enterprises flexibility in planning the evolution of their IP and voice infrastructure and prepare for a simple transition to cloud-based telephony or pure SIP Trunking.
