Communications Manager.
Design Considerations
Before you register any Polycom RealPresence video endpoints to Cisco Unified
Communications Manager, consider the following information about interoperability between
CUCM and Polycom systems.
Cisco Unified Communications Manager Considerations
Make note of the following CUCM considerations:
• Location settings should allow for video bandwidth when integrating Polycom video
endpoints and infrastructure.
• Region settings should allow for a minimum of 256k video bandwidth (region settings
should match the Polycom HDX system maximum call rate).
• Region settings should allow for a G.722 audio protocol for the best audio experience.
• The Polycom HDX system should be added to a device pool in which the Media Resource
Group List does not contain MTP resources.
