| Message | What is a VoIP codec?
A codec (Coder/Decoder) converts analog signals to a digital bitstream, and another identical codec at the far end of the communication converts the digital bitstream back into an analog signal.
In the VoIP world, codec's are used to encode voice for transmission across IP networks.
Codec's for VoIP use are also referred to as vocoders, for "voice encoders".
Codecs generally provide a compression capability to save network bandwidth. Some codecs also support silence suppression, where silence is not encoded or transmitted. |
