Diagnostic Tests
Synthetic Tests
Synthetic testing is a mechanism by which Operations Manager emulates a phone. For example, Operations
Manager makes phone calls, logs into conferences, leaves voice mails, makes emergency calls, and downloads
TFTP files.
Note:
MAC addresses for synthetic phones must be between 00059a3b7700 and 00059a3b8aff.
When a synthetic test is unsuccessful, it generates one of the following events:
●
SyntheticTestFailed: Individual test failed.
●
TooManyFailedSyntheticTests: Out of a sample of four tests, the actual percentage of tests that failed
exceeds the value of threshold.
●
MWIOnTimeExceeded: Number of seconds in which the Cisco Unity message waiting indicator (MWI) light
appears exceeds the value of the MWI on-time threshold.
●
SyntheticTestsNotRun: Tests were not run for more than 10 minutes on the Operations Manager server
(possibly because of insufficient CPU).
Synthetic tests are supported on a variety of applications: Cisco Unified Communications Manager, Cisco Unified
Communications Manager Express, TFTP Server, Cisco Conference Connection, Cisco Emergency Response,
Cisco Unity, and Cisco Unity Express. The synthetic tests can be scheduled to be run on a periodic basis.
Synthetic Test Descriptions and Expected Results
Table 3 describes the synthetic tests and gives the expected results.

End-to-End Call
Initiates a call to a second simulated or real IP phone.

Destination phone goes off-hook to accept the call.
If call progress tones and announcements are
configured on the gateway for your end-to-end call, the
test may succeed even before the phone rings or after a
couple of rings.

This indicates that your gateway is working correctly. It
can also confirm that the destination route pattern is
correct.

The registration of the phone occurs only during the first test

Enable RTP transmission: Operations Manager plays a
recorded announcement upon answer. Use this feature in
conjunction with the Cisco 1040 Sensor and Service Monitor
to monitor the quality of voice (QoV) of the test call.
