VoIP Codec – What is it?

Acronym that stands for "compression/decompression

Essential part of VoIP

Codecs are used to convert an analogue voice signal to a digitally encoded version.

Codec will compress the information. The compression level varies between codecs

Codecs vary in the sound quality and the bandwidth required

VoIP equipment will negotiate which codec to use unless specified


VoIP Codecs - Continued

There are many codecs that can be used.

Not of all them are used.

Telecomplete use the following codec’s for our VoIP service:

G.711

Wide scale support

The best quality codec

Uses 64Kbps


VoIP Codecs ContinuedG.723

Widely used codec
