When a call comes in from a gateway that is configured as OnNet, the system sends the inside ring to the destination device. • Use System Default - When you choose this field, this uses the Unified Communications Manager clusterwide service parameter Call Classification. Note If you have enabled clusterwide restrictions an all trunks, configure each trunk to Use System Default (this reads the setting in the Call Classification service parameter and uses that setting for the trunk) Step 5 Click Save.
