Cloud phone systems are without doubt the future of communications and should be considered mandatory for every company that wants to reduce expenses. However, just like anything else, VoIP is also a product with countless variants: in other words, you want to see what your options are and how the chosen solutions perform. VoIP providers don't offer free trials because of the process of ordering and transferring phone numbers. Many companies do offer a money back guarantee, which is basically the same.
This is the method that RingCentral also uses to give you the chance of trying its cloud phone system free of charge. You just have to subscribe to a pricing plan and if you are not satisfied, just cancel it within 15 days. RingCentral will be sad to see you go, but will keep its promise and refund every single dime you paid for its services.
