[cisco-voip] Ответ: Conference with G.711 and G.729

[Daniel A. Abelski]

CallManager can`t transcode 711 to 729 and vice versa. You can use a
hardware MTP - that is DSP on a GW, you can use one of your SCCP
controlled MCU if you have any and you can use meetingplace express
2.0 for that. It supports 711 and 729.
