Transcoding

Transcoding is the conversion of call media from one voice encoding algorithm (also known as a codec or a vocoder) to another. This is done to bridge differences in capabilities between telecommunications systems supporting the calling and the called parties. For example, when two end point devices involved in a call do not share a common vocoder among their vocoder sets.

TelcoBridges and Transcoding

TelcoBridges devices support transcoding among a number of popular voice codecs whether during calls from TDM-to-IP networks, IP-to-TDM networks or IP-to-IP networks featuring different end-point device capabilities.
