all, of its addresses are up. An address is considered down if its response to OPTIONS is:
• 408 Request Timeout
• 503 Service Unavailable (with no parenthetical text)
• 503 Service Unavailable (LSP is inactive)
• 503 Service Unavailable - System Busy

You can turn monitoring on or off for a given SIP entity. If monitoring is turned off, the SIP entity
is not monitored by any instance.
You can also turn monitoring on or off for an entire instance. If monitoring is turned off, none
of the SIP entities are monitored by that instance. If monitoring for the instance is turned on,
only those SIP entities for which monitoring is turned on are monitored.
SIP Monitoring can only report problems if the Security Module is functional.
SIP Monitoring setup is administered through the Routing Policy screens on the System
Manager.

About this task
The SIP Entity Link Monitoring Status Summary page displays the status of the entity links for
all administered Session Manager instances. An entity link consists of one or more physical
connections between a Session Manager and a SIP entity.
If all of the connections are up, then the entity link status is up. If one or more connections are
down but there is at least one connection up, the link status is partially down. If all of the
connections are down, the entity link status is down.

Link monitoring status for all Session Manager instances.
