Cluster in Singapore makes two calls to USA via USA CUBE Router onnet, hits conf button, conf call shows connected, then in about 5 secs disconnects and displays "Cannot Join Calls" Debugs attached, have tried another remote resource with no luck.

CM Trace shows cfb resource, C070003FEADC924,(which is the HW_CFB in Remote Cluster) the phone doing the conferencing is 7498510, called parties are 9374453675 and 9374456115.

Your help is appreciated.

Are you using Software Conference Bridge? SCB only supports G.711 codec, so probably you have configured to talk G.711 within the same site and G.729 with the remote sites and that is why you are not allowed to join those phones to the conference.
