4S IP PBX
The 4S IP PBX is a product package based on the 4S proxy and the 4S media server.
It allows users to migrate from traditional PBX-based telecommunication systems to modern service-oriented VoIP technology.
This software provides the complete set of functions users expect from traditional PBX devices and more.
As it is a pure software solution it can be easily configured and adapted to almost any telecommunication requirement and scenario.
For example, if you move offices: just a couple of minutes work on the web interface of the software and you are reachable under your old number and can start using your VoIP infrastructure.
The 4S PBX is designed with scalability in mind and is therefore especially suited for businesses with many branch offices. These are the types of businesses that stand to benefit most from VoIP.
Depending on your network topology, the 4S IP PBX can also be used to provide hosted PBX (IP-Centrex) services.
