VoIP Interview Question:

How does VoIP (voice over Internet protocol) work? What makes it different from traditional phone service?

Submitted by: Administrator

Traditionally, a phone conversation is converted into electronic signals that traverse an elaborate network of switches, in a dedicated circuit that lasts the duration of a call. In Voice over Internet Protocol, a conversation is converted to packets of data that flit all over the Internet or private networks, just like e-mails or Web pages, though voice packets get priority status. The packets get reassembled and converted to sound on the other end of the call.

A technology that allow packet data transmission, includes both "DATA" & "VOICE" calls. This reassembles together to carry as sound signal.
