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.

Communication Manager

Avaya Aura(R) Communication Manager is a private branch exchange that transfers calls
between VoIP users on local lines while all users share a certain number of external phone
lines. Communication Manager can also move calls between a VoIP user and a traditional
telephone user.
With Communication Manager, you do not require a separate network for voice and data
communications. CM employs converged data and voice networks. Converged networks make
Internet access, VoIP communications, and traditional telephone communications possible
using a single line to each user.
