monitoring of an agent consumes almost the same network bandwidth as an
additional voice call. If a single agent requires bandwidth for one voice call,
then the same agent being silent monitored requires bandwidth for two
concurrent voice calls.
example, assume the following:
case, plan for network capacity for 100 + (20% of 100) concurrent calls, or 120
calculate the total network bandwidth required for your call load, you would
then multiply this number of calls by the per-call bandwidth figure for your
particular codec and network protocol.
example, the table on the Cisco Voice Over IP-Per Call Bandwidth Consumption
website lists the per-call bandwidth on the G.711 codec (for a call with the
default voice payload size) over Ethernet as 87.2 Kbps. You multiply this 87.2
Kbps by 120 calls to obtain the total required network bandwidth.
