Which CAR module report provides key information to determine if an additional gateway is needed?

The Gateway Utilization report in CAR calculates the percentage of time a gateway's ports are actively handling calls during a defined period, directly revealing whether a gateway is operating near its capacity limit. A consistently high utilization percentage is the key data point that justifies provisioning an additional gateway to handle call volume.

The Gateway Summary report provides aggregated call counts and durations per gateway but does not express port-level utilization percentages needed to assess whether capacity is being exhausted.

The Gateway Detail report lists individual call records routed through each gateway, which is too granular for capacity planning and does not produce utilization trend data.

The Gateway and Line Group Utilization report focuses on line group capacity analysis rather than isolating individual gateway port utilization as required for gateway-specific capacity decisions.
