Hope someone can lend some help. I have central callmanger v4.1 with remote locations connected with H.323 gateways. Users can not transfer calls to a location by extension, it causes the voice to be one way only. Or when trying to place into conference this site gets disconnected with fast busy. I have seen posts regarding Media Termination Point Required being checked, it is checked for this gateway. Thank you
Those might be 2 different issues, have you looked at codec issues for the conference problem.
For the transfer if this only happens when you try to transfer to another location over WAN link and does not happen within same location, as Paolo mentioned, making sure there is connectivity for the RTP would be the first thing to check.
