IP-PBX
The IP-PBX is a private branch exchange that switches calls between VoIP users on local lines
while allowing all users to share a certain number of external phone lines. The typical IP-PBX
can also switch calls between a VoIP user and a traditional telephone user.
With a conventional PBX, separate networks are necessary for voice and data communications.
One of the main advantages of an IP-PBX is the fact that it employs converged data and voice
networks. This means that Internet access, as well as VoIP communications and traditional
telephone communications, are all possible using a single line to each user. This provides
flexibility as an enterprise grows, and can also reduce long-term operation and maintenance
costs. Like a traditional PBX, an IP-PBX is owned by the enterprise.
