bandwidthLimit0-2147483647, or unlimitedThe total media bandwidth limit, in Kbits/sec. (default = "unlimited")
bandwidthLimitThreshold0-100Enter threshold value (as a percentage) to specify bandwidth utilization notification threshold. (range: 0-100 / default = 0)
bandwidthVideoThreshold0-100Enter 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. (range: 0-100 / default = 0)
callLimit0-2147483647, or unlimitedTotal number of concurrent calls (either ingress or egress) allowed. (default = “unlimited”).
callLimitThreshold0-100Call Limit utilization notification threshold, as a percentage. (default = 0)
