H.239 / People+Content
The H.239 protocol allows compliant endpoints to share content. All Conferences,
Entry Queues, and Meeting Rooms launched on the RMX have H.239 capability.
People+Content utilizes a different signaling protocol and is Polycom’s proprietary
equivalent of H.239.
Guidelines
H.323 environment is supported.
Conferences can include a mix of endpoints that support H.239 or People+Content.
All endpoints will receive Content at the highest resolution common to all
connected endpoints.
SIP People+Content is supported with MPM+ and MPMx cards.
H.239 is supported in MIH, Star and Basic Cascading topologies.
People+Content is supported in cascaded conferences but cannot be used as the
protocol for a cascade link.
If an endpoint supports both H.239 and People+Content protocols, H.239 is selected
as the preferred communications protocol.
People+Content is enabled by default. It can be disabled for all conferences and
endpoints by manually adding the ENABLE_EPC System Flag to the System
Configuration and setting its value to NO (default setting is YES).
Endpoints that support People+Content (for example, FX endpoints) may require a
different signaling protocol. For these endpoints, manually add the System Flag
CS_ENABLE_EPC to the System Configuration and set its value YES (default value
is NO).
G.728 Audio Algorithm Support
Industry standard G.728 audio algorithm is supported for participants connecting with
legacy or low bandwidth endpoints.
Guidelines
G.728 is supported:
•with MPM+ cards only
in mono
•in H.323 and ISDN networking environments
at bitrates from 64kbps to 4096kbps
Monitoring Participant Audio Properties
The audio algorithm used by the participant’s endpoint can be verified in the
Participant Properties - Channel Status dialog box.
