Know More About VoIP Technology And IP Telephony
VOIP (Voice over Internet protocol) is a device to transfer voice over IP (internet protocol) by digitizing voice into discrete packets that are transferred independently over the network, instead of traditional circuit-committed protocols of the PSTN. Broadband phone is a familiar name for VOIP which is similar to a telephone but economical in nature. The user can directly use a VOIP through his computer or a telephone device connected to computer. The analogue electrical signal is sampled at regular intervals (e.g. 8000 times per second) and each sample is assigned a binary number – typically 8 bits long. The binary data is assembled into small packets and inserted into the data field of the IP packet and sent to the destination.
