What is Transcoding?
To save bandwidth, VoIP Network engineers sometimes compress the voice signal
This is done using CODECs
Codecs are algorithms (a lot of math) to compress voice signal
Sometimes called Vocoding
Voice Codecs:
G.711, G.729, GSM, AMR, G.726, iLBC, G.722.1, etc.
Most common in use in wired world are:
G.711 (64kbps) / G.729 (8 kbps)
Most common in use in wireless applications:
GSM / AMR
Growing in popularity – G (HD voice)
