VoIP Design Issues

One of the primary advantages of using IP to transmit voice is the ability to use the same infrastructure to transmit voice and data traffic. VoIP involves converting voice into data packets and encapsulating them in IP format. This allows the same router and Ethernet switch fabric to transmit voice and data.

Voice communication is more sensitive to delay, inconsistent timing and packet loss than most data traffic. For example, if two computers are communicating over a network they can adjust to delays in packet transmission, use higher-level protocols to sequence packets, request retransmission of lost packets, and use error correction to retrieve corrupt packets. These techniques are not effective in correcting voice quality. Networks that converge voice and data must be designed to insure the efficient movement of voice packets through the network.

VoIP has implications for network security policy. Nat servers and Firewalls create difficulty for VoIP gateways and endpoints. In addition, a network virus can severely deteriorate VoIP transmission
