G.729 Codec
The G.729 Codec page allows you to register and manage your G.729
codec license keys. The G.729 Codec is an industry standard algorithm
that compresses and decompresses a digital audio stream. Applied to
Voice over IP (VoIP) calls, G.729 compresses the audio data to use
significantly less network bandwidth than a standard or uncompressed
VoIP call. This compression allows for more calls to be carried without
increasing network capacity and allows voice to travel on limited-
bandwidth connections that would otherwise not support VoIP.
Note: The Asterisk Appliance 50 can support a maximum of 8
simultaneous calls being transcoded with G.729. Calls using G.729
which are not being transcoded (pass-thru) do not count towards that
total.
