Voice over Internet Protocol (VoIP) technology utilises a company’s local area network (LAN) to make and receive phone calls via a broadband internet connection instead of the traditional, more expensive analogue phone line (PSTN).

The traditional business telephone solution is showing its age. In lieu of the Internet and online technologies like the cloud, organizations are finding it difficult to justify keeping a traditional phone line for their communications solutions. Considering how difficult and expensive it is to scale a traditional PBX phone system to accommodate for growth, businesses want a more dynamic solution that’s in line with their current and future needs.

With a cloud VoIP solution from RCS, your business can finally cut expensive telephone services out of your budget, and replace them with flexible solutions designed to address your organization’s communications needs. By taking advantage of a service that you already use - the Internet - to secure the communication platforms your company requires while removing unnecessary service costs.
