We received a network broadcast between our 5600 PBX and CTGateway. At the end of it, we received insufficient bandwidth errors on four phones (at least one of them lost the call) and our Filed Based MOH stopped playing. I'm afraid I don't have more information than that. We were not storing the data stream of the network broadcast, so I can't tell you the content. A reboot, after hours, reset the MOH. In the meantime, I had to change the camped on audio to ringback. Our callers were hanging up when they heard only silence.
