Most phones on a VoIP system are routed or attached through a
Public Branch Exchange (PBX) or Computerized PBX (CPBX). The PBX
delivers calls to a VoIP gateway (a dedicated server (a device)
or a Cisco router. Advantages of VoIP: cost (inexpensive long
distance calls), quality (equal to PSTN in good situations), and
convergence (integration on a single network).
