The MAC address for synthetic phones must be between 00059a3b7700 and 
00059a3b8aff. 
Synthetic testing is a mechanism by which Operations Manager emulates a phone. For 
example, Operations Manager makes phone calls, logs in to conferences, leaves voice 
mails, makes emergency calls, and downloads TFTP files. When any of these operations 
fails, Operations Manager flags the failure as an alert, letting the operations personnel 
know that there could be a problem.  
Synthetic tests are supported on a variety of applications: Cisco CallManager, Cisco 
CallManager Express, TFTP Server, Cisco Conference Connection, Cisco Emergency 
Response, Cisco Unity, and Cisco Unity Express. The synthetic tests can be scheduled to 
run on a periodic basis. 
 

Phone 
Registration  

Opens a connection with 
the Cisco CallManager/ 
CallManager Express and 
registers a simulated IP 
phone.  

Successful registration of the phone.  

Off Hook  

Simulates an off-hook 
state to the Cisco 
CallManager/CallManager 
Express and checks for 
receipt of a dial tone.  

Receives a dial-tone signal from the Cisco 
CallManager. The registration of the 
synthetic phone takes place only for the first 
time because registration is a costly 
operation on Cisco CallManager. (However, 
if the test fails, then synthetic phones are 
registered again for the next test cycle only.) 
Once the synthetic phone is registered, 
Operations Manager checks for a dial-tone 
signal from the Cisco CallManager.  

End-to-End

simulated or real IP 
phone.
