What is an IP PBX?

IP-PBX stands for Internet Protocol – Private Branch Exchange.

A traditional business telephone system uses private branch exchanges (PBXs) to relay telephone signals from station to station or from stations to the global public switched telephony network (PSTN) over its network. A PBX system can span more than one location.

An IP-PBX connects the PBX network to a VoIP-based system so you can access any stations or the PSTN from your VoIP telephone network. The IP-PBX also provides you with telephony features on your VoIP network, including automated messaging, teleconferencing, voice mailboxes, and so on.
