Explanation
Cisco WebEx Enabled TelePresence (WET) allows WebEx meeting participants to join TelePresence room sessions. Interoperability between the WebEx cloud infrastructure and TelePresence endpoints requires specific codec support: G.711 for audio (uncompressed, high-quality audio that both platforms support natively) and H.264 for video (the standard high-definition video codec used by TelePresence systems). G.729 is a compressed audio codec and is not required for WET. H.263 is an older, lower-quality video codec that is not required. The WET architecture mandates G.711 and H.264 specifically to maintain consistent audio/video quality across both environments.
