With our Business Fair Flats, youʼve got cost security. Just buy the minute packages and get a discount of up to 71 percent on your minute-based billing. The minutes apply to all registered devices. Compared to other offers (where you book one flat rate per extension), you will significantly save. After your included minutes are used up, you keep on calling at the affordable rates of easybell. If you combine the SIP trunk Business plus with the minute packages Fair Flat L or XL, you get 50 instead of 30 lines. In the Office Komplett Trunk all-in tariff, you receive for 10 €/month with the Fair Flats S and M 30 lines and with the Fair Flats L and XL 50 lines. You can terminate the Fair Flats on a monthly basis.
