Analog to Digital Conversion (ADC) – This is the process of changing your voice, All calls over a VoIP network will pass through a voice codec which in There are two main types of audio compressions in VOIP codecs, lossy and Sampling rates from 8 kHz (narrowband) to 48 kHz (fullband); Frame sizes from
The IP Profile object in the Web UI is used to define a set of VoIP Parameters displays the codec as well as the minimum and maximum payload sizes that can
G 729 and G 711 are voice-over-internet-protocol (VoIP) phone codecs, which are programs that compress the sound of your voice for easier transmission during an internet phone call, decompressing it on the other end. G 711 has better quality but requires more bandwidth while G 729 requires less bandwidth, but quality suffers as a result. Selecting the best codec always involves some compromise between bandwidth consumption and audio/video quality. The codecs most commonly used for Voice over IP are G.711 and G.729. Other less common VoIP codecs include G.722, G.723, G.726, GSM, iLBC, Speex and SILK (used by Skype). We make a lot of AoIP codecs, all designed to satisfy different needs.

First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs, is the date of first binary releasing. Many developing codecs have pre-releases consisting of pre-1.0 versions and perhaps 1.0 release candidates (RCs), although 1.0 may not necessarily be the release version.
