Zone name is unique across all address contexts. |
cac

bandwidthLimit
bandwidthLimitThreshold
bandwidthVideoThreshold
Enter threshold value (as a percentage of video bandwidth) to limit video streams to a specific bandwidth to prevent video calls consuming call bandwidth otherwise needed for audio calls. (default = 0)
