Description (partial)

A DX650 endpoint connecting remotely to CUCM over a VPN connection on an untrusted network will attempt to contact CUCM, CUC, and potentially other collaboration services before the VPN connection is established, even if "Always on VPN" is configured on the endpoint. This exposes potentially sensitive internal IP addressing on an untrusted network.
