Cloud services eliminate the need to maintain complex and increasingly outdated hardware and pay expensive technicians for time-consuming repairs. The phone systems of old rely on PBX hardware in this fashion. Now, businesses of all sizes can get much more than a phone system with RingCentral cloud communications. Voice is only the tip of the iceberg, and other features available include conferencing, fax, team messaging, and much more. Security and reliability standards are high, while costs are drastically reduced.
