Any business can technically implement their own VoIP phone solution with the right combination of IT infrastructure to support VoIP technology and the skills and knowledge to make it happen. Unfortunately, the amount of capital investment needed to do that is staggering. Cloud communication service providers like RingCentral are able to offer businesses VoIP services with advanced features like cloud PBX, automated-attendant, answering rules, call forwarding, hold music, caller ID, call blocking, and more with flexible plans and pricing by hosting the services on their own secure, multi-tiered, and redundant cloud IT infrastructure and leveraging the internet for delivery of service.
