VoIP PBX for Windows


A VoIP PBX or IP-PBX is an IP phone system that completely replaces and upgrades your proprietary PBX. A VoIP based system is software-based, thus reducing call costs as it uses any IP network for the VoIP data transport. Traditional PBXs are hardware-based and in the vast majority of cases uses proprietary hardware and copper pair based telephone lines.

The caller can use a software-based SIP phone (a software application installed on your computer), an Internet phone, or a normal telephone that is connected to the internet and the IP-PBX server by a specific adapter for the SIP protocol (Session Initiation Protocol). This increases convenience as it allows users to easily work remotely.

It is based on the SIP standard and supports most popular SIP phones, VoIP Gateways, VoIP service providers, and PSTN phone lines.
