Description
Selecting a new conference line rate lower than the initial line rate selected for the conference (for
example, changing from 4096 kbps to 1532 kbps) may result in system reverting to the default
resolution for that line rate (for example, 720p instead of 1080p). You may need to select the
required resolution again, provided the selected line rate is higher than the minimum threshold line
rate defined for that resolution in the system configuration. For more details, see “Minimum
Threshold Line Rate System Flags” below.
