Endpoint Registration Options - Content Sharing Experience
● H.239
A variety of resolutions and frame rates are supported.
For more information see Content Sharing Using H.239 Protocol and Content Sharing Using
People+Content Protocol.
Can be used with SIP and H.323 endpoints, desktop (CMAD), room systems (HDX) and ITP
(OTX, RPX).
Not supported by Lync clients, IBM clients and Cisco CTS endpoints.
Cannot be used when HDX endpoints are registered to CUCM.
● TIP
The resolution is fixed at XGA at 5fps, 512 Kbps.
Supported on HDX, Polycom ITP and Cisco CTS systems.
● The following content compatibility options are available:
None (TIP not enabled) – TIP endpoints cannot join the conference.
Prefer TIP - Both TIP and non-TIP endpoints can share content via H.264, base profile, using
resolution and rate as described above.
For more information see Procedure 4: Configuring a TIP Enabled Profile on the Collaboration
Server.
Procedure 1: Set the MIN_TIP_COMPATIBILITY_LINE_RATE System Flag
The MIN_TIP_COMPATIBILITY_LINE_RATE System Flag determines the minimum line rate at which an
Entry Queue or Meeting Room can be TIP enabled.
CTS version 1.9.1 is required, and if CUCM is present in the environment, a minimum line rate of 1280 kbps
must be set in the conference profile. Calls at lower line rates are rejected, therefore the System Flag value
must be set to 1280 or higher.
HD Video Resolutions for TIP calls are determined according to the following table:
