The Link Monitoring from Peer option is used to support the Avaya Aura® SIP Resiliency feature. Avaya SBC must support the SIP Resiliency feature in the OPTIONS response Contact header. Session Manager should know the SIP Resiliency supported for neighboring elements to change the call/message sequence behavior for the Session Manager failover/failback scenarios.
When Link Monitoring from Peer is enabled, Avaya SBC sends a success (200OK) response if the OPTIONS request is matched to that server flow.
When Link Monitoring from Peer is disabled, the OPTIONS request is relayed to the destination server.
