Explanation

The ip address trusted list configuration under the voice service voip section in Cisco Unified Border Element (CUBE) defines which IP addresses or subnets are allowed to send SIP requests to the CUBE. If the source IP address of an incoming SIP message is not in the trusted list, the CUBE rejects the connection. The trusted list allows SIP connections only from 192.168.101.201, as it matches the subnet 192.168.101.0/25 in the configuration.
