How the Service Works

With the advance of globalization, the main issue that must be addressed is to minimize the cost of international calling. If you implement the SIP Trunking Plan, you can call any overseas clients or partners without worrying about the quality and costs.

The SIP Trunking Plan will enhance your global communication.

You might find yourself installing the voice and data networks separately in each global office.

Paying too much money on maintenance and wasting too much time on operations are serious problems. If you implement the Arcstar SIP Trunking, you can reduce total cost of ownership and save time of operating separate networks by combining voice and data communications over Arcstar Universal One (secure MPLS-Based VPN).

You need to reduce growing voice call expenses at your global organization.

While the "Arcstar UCaaS" will reduce internal call costs among global offices, the "Arcstar SIP Trunking" will do so for external call costs to partners and / or clients worldwide.The Arcstar UCaaS offers a unified workspace together with high quality networks on a global scale, and will enhance global collaboration.
