Events related to phones
When a phone becomes unavailable, an event will be logged. This event
can have two causes:
The phone stopped responding to the IP Ping Service: This event only
applies to phones that have an IP address assigned. This event resolves
when the phone responds to the IP Ping Service again.
The phone status has changed to Offline: 3Com Network Director
polled the NBX Call Processor and found that the phone Status is now
Offline. This event resolves when the phone status changes.
Events related to other links or devices on the network
Even if both the NBX Call Processor and the phones are available, some
network conditions might cause calls to be dropped, or result in a loss of
voice quality noticeable as delays or jitter. For instance, the following
network conditions could affect the voice network:
High number of packets being dropped on switches
High number of error frames on links
High link utilization
Switch becomes unavailable
In all these cases, an event will be logged. Details shown for this event
will include information such as:
What might be the cause of the problem
What effect this may have on the voice network
How to resolve this condition
The events resolve when the network condition becomes acceptable
again.
