Ive also got an issue where neither ad hoc nor meet-me conferencing is not working. I have CUCM 6.1.3, and I have the software setup, and devices, device pool, etc all in the same partition. I do not have conferencing resources setup on the gateway, which all should be using g711 internally. I know this may be a bit vague, but has anyone see this as well? By the way, this is BE.
