About VoIP for business

Utilising the latest technology in IP communications, Optimus Systems can offer a customised VoIP service ranging from a simple telephone setup to a complex hosted PBX environment. Our VoIP service provides consultation and network design through to hardware and software deployment, helping you to develop your communications platform and provide a cost effective and feature-rich telephone solution.


VoIP enables SMEs to streamline and enhance their telecommunications while reducing their cost of ownership. With VoIP technology, small businesses now have a viable alternative to the traditional business phone system that facilitates a more mobile workforce and a powerful communications feature set for a fraction of the cost of both traditional phone lines and onsite PBX systems.

How it works

A VoIP Phone System / IP PBX system consists of one or more SIP phones / VoIP phones, an IP PBX server and optionally includes a VoIP Gateway. The IP PBX server is similar to a proxy server: SIP clients, being either soft phones or hardware based phones, register with the IP PBX server, and when they wish to make a call they ask the IP PBX to establish the connection. The IP PBX has a directory of all phones/users and their corresponding SIP address and thus is able to connect an internal call or route an external call via either a VoIP gateway or a VoIP service provider to the desired destination.


At the centre of it all we have our cloud based PBX system hosted in our datacentre’s that connect to trunks that allow you to make calls. This takes away the requirement for you to have costly hardware onsite you have to service and maintain and removes the complexity when you want to either mange an extension, view reports or reconfigure your call-flows. The possibilities are endless.


From there you can connect remote extensions in the form of computers running the softphones, physical IP Phones in any of your offices or even home offices, and mobile devices running our Android and iOS clients.
