Explanation

SIP Options Ping causes Cisco Unified Communications Manager to periodically send SIP OPTIONS messages to the remote SIP trunk destination. If the remote device fails to respond, CUCM marks that destination as out of service and automatically routes calls to the next available device (such as the failover device). Manual monitoring (option C) introduces human delay and is not a reliable automated solution. ANAT relates to dual-stack IPv4/IPv6 negotiation. Transmit security status is unrelated to failover routing.
