What is VoIP Codec?

Posted by 5 September, 2018 Comments Off on What is VoIP Codec?

A codec refers to an algorithm that is used to decode and encode voice conversation in VOIP. The sound and voice that human beings hear is in analogue form and has to be converted to digital to make it possible to transmit it over the internet. The sound or voice has to be converted back to analogue once it reaches the receiving end so that it can be heard.

VoIP Codec

There are various ways that the decoding and encoding can be done but the majority of them use compression. This method ensures that the bandwidths are reduced. If the compression is heavy, there is usually a delay in the conversation because it takes time. It is possible to find a VoIP codec that will take a minimum amount of time.

RJ stands for Registered Jack and refers to a physical connector that is used as an interface for wire terminals used in telephones. It has six connector positions but generally two or four are used. This means that the extra wires can be used for various applications such as grounding selective ringers. The wiring for this connector comes in two varieties. One is the untwisted and the other one is the unshielded twisted pair.

This is one of the most popular registered jacks and is used in a majority of the telephone jacks that have a single line. It is similar to the RJ14 and the RJ25 except that the numbers of lines are different and it has a powered version.
