â¢Lower cost of ownership-The Cisco VG200 communicates with the Cisco CallManager using the Media Gateway Control Protocol (MGCP) or H.323 Version 2. It allows connectivity between a Cisco CallManager-based IP telephony system and legacy telephony equipment such as the PSTN, private branch exchanges (PBXs), and voice-mail systems. The Cisco VG200 provides a space-saving solution that can be managed remotely using network management applications such as CiscoWorks.
as you mention, CUCM version is really not relevant.
