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 7 requires a minimum line rate of 1024 kbps and will reject calls at lower line rates, therefore
the SysCollaboration Servertem Flag value must be 1024 or higher.
HD Video Resolutions for TIP calls are determined according to the following table:
TIP HD Video Resolution by Line Rate
