User's Manual
12.1.2.2 Status and Performance Monitoring
The ability to remotely monitor the status of MP-20x is critical to the service provider, who
wants to support users without having to send a technician on site (avoiding the "truck
roll"). The service provider may want to know the current status of MP-20x (e.g. is it
registered to the SIP proxy, is the phone off-hook) or some statistical information (e.g.
average packet loss during a call).
MP-20x maintains a set of status and performance information internally. This information
(or parts of it) can be retrieved via the different management interfaces (e.g. Web, SNMP,
or TR-069).
The table below describes the status and performance monitoring (statistical) information
available in MP-20x, divided into the main groups.

12.1.2.3 Alarms, Notifications and Logging
Instead of periodically polling MP-20x to obtain its current status, the service provider may
want MP-20x to notify abnormal events or to send regular reports to a logging server. Both
options are supported by MP-20x. The table below shows the relevant interfaces for alarms
and notifications.
