Note: Insertion of Media Termination Point Resources
Due to the nature of out-of-band DTMF signaling, Cisco Unified Communications Manager
is capable of inserting a Media Termination Point Resources (MTP) in a call. This will
prevent video on the Polycom HDX system from operating correctly. This is most common
on H.323 and SIP trunk calls. To prevent this from occurring, the MTP resources should
be removed from any Media Resource Groups and Media Resource Group Lists that
would be used in the trunked calls.
Polycom Immersive Telepresence Systems Considerations
The Telepresence Interoperability Protocol (TIP) provides a means for multi-screen or multi-
camera video systems to provide proper video alignment and spatial audio capabilities with
other multi-screen/multi-camera endpoints. For multi-screen, immersive system connectivity,
consider the following:
• The TIP option key is required in order to support TIP calls. Polycom telepresence
endpoints support TIP version 7.
• If you have a Polycom ITP system, the TIP license is included, however ensure that the
TIP option key is installed on each HDX system.
• Each codec in a Polycom ITP system must be registered with CUCM.
• In order for Polycom ITP endpoints to participate in calls hosted by the Cisco
TelePresence Server, you must predefine them on the Cisco TelePresence Server.
Content Sharing in Telepresence Environments
Within a Cisco telepresence environment, Polycom and Cisco endpoints can share content in a
separate content channel.
The following guidelines apply:
• Content sharing within a Polycom/Cisco environment is limited to XGA at 5 fps.
• In point-to-point calls between Polycom endpoints registered to CUCM, content can only
be sent and received in the video (people) channel.
• In multipoint calls hosted by the Polycom RMX system, Polycom endpoints registered to
CUCM cannot send content to or receive content from Cisco TelePresence Systems
(CTS) connected to the conference.
• Content sharing on Polycom ITP or HDX systems is only supported via VGA cable. USB
content sharing is not supported.
• Polycom People + Content IP tool is not supported in Cisco telepresence environments.
Device Licensing
Device license units are assigned to each device connected to Cisco Unified Communications
Manager. Each device is assigned a unit number based on the type and capabilities of the
