Cloud telephony is relevant in a business context and is also known as cloud calling, which is a type of unified communications as a service (UCaaS) that offers voice communication services. The capital expenditure in setting up a telephony system (be it a VOIP-based internet telephony system or a PRI/PSTN-based PBX system) is high.
