G.729D for VoIP appl. - Andi Mardiansyah - Jun 2 12:29:00 2002

Hi all The G.723.1 and G.729/A are usually used in VoIP application, many gateway product use those algrtm. Anyone know why G.729D is rarely / not used for VoIP? Is that just because G.723.1 came earlier than G729D or there are some technical reasons? G.729D has 6,4 kbps bit rate ( lower than G.723) and faster algorithm delay, why VoIP appl. dont use this? Thanks Andhi M |
