What is Business Telephony?

An inOne SME subscription gives you the option to use Business Telephony, so you can make calls using your landline number, even when you are out of the office. Incoming calls can reach you on your mobile phone or PC/laptop on your fixed-network number. This service requires an app for your smartphone or a client for your PC/laptop.

Setting up the app/client

Download the app or client so you can still be reached on your fixed network number even when you are on the move.
