VoIP Transcoding Solutions
Transcoding refers to the conversion of call media from one voice encoding algorithm (also known as a codec or a vocoder) to another. This is performed in order to bridge differences in capabilities between the telecommunications systems supporting the calling and the called parties. For example, when the two endpoint devices involved in a call don’t share a common vocoder among their vocoder sets.
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.
