VoIP bandwidth requirements

1. VoIP bandwidth depends on the codec of your IP address of uses.Voice software or VoIP technology, is to send and received by the human voice over IP (such as the Internet itself) designed.

Since the human voice of no absolute loyalty requires takes the same amount of bandwidth to VoIP to, say, submit requires be understood, live music on an IP network acceptable detail. What are the bandwidth required varies depending on the algorithm used to encode the signal.

Silent

VoIP information sends and receives is in the form of "Packages".

Keep in mind as for calls that silence probably contain times is that it is VoIP not consistently pass packages; This is when VoIP is picked up very noise at all just bandwidth used.

Header

Each package of VoIP requires a "header", a collection of technical information are always 320 bits in size.

How much of a load that places it on the bandwidth depends how many packets per second —, which in turn are sent, is from sounds as great a piece represents each package. Smaller, more frequent packet payloads mean more data header and therefore more bandwidth use. larger and less common fees mean transmission delays.

Codecs

The determinant of the VoIP bandwidth requirements is the codec that uses the software.

A codec (compressor/decompressor) is a piece of software that and at one end of a transmission encodes a signal and decompressed and decodes at the other end. Several different VoIP codecs are available, and (c) veryone produce packages of various sizes, which means different NutzlAsten and different number of headers per second. Requirements to the frames per second (KBPS) to as low as 28 kbit bandwidth of popular codecs or higher than the g. 711 87 K / s will be documentation audit software of VoIP, your resources for more information on what codec to use and a codec table to check such as the associated bandwidth this codec.
