Description

[Overview]
Smart PBX is an IP phone service that you can use on your smartphone. It is a mobile device service that is provided as a major additional function of mobile communication services such as "OCN Mobile ONE for Business" and dedicated line services such as "Arcstar Universal One" provided by NTT Docomo Business for businesses.

By using this app, users of communication services provided by NTT Docomo Business such as "OCN Mobile ONE for Business" can make calls at low cost, and can also use the basic IP phone service functions of "management of call history" and "switching between the default phone and this app depending on the purpose".

By using this service, you can make calls using extension numbers not only within the base, but also between bases and when you are out. In addition, customers can change the settings of extension numbers, representative groups, forwarding, answering machines, etc. by themselves, and it is a one-stop service that allows you to use PBX functions.
