 Managerial Features

Trace Call lets you record a caller’s telephone number on a system 
printout. You can trace a call manually and then ask your system 
administrator for a printout of the number. Or, if Automatic Trace Call 
has been assigned to your telephone’s class of service, all calls to your 
telephone are traced and their numbers printed at the communications 
server.

After the caller has hung up, listen for the

For Trace Call to work, the number of the call being traced 
must be an extension or must be made available to the 
communications server by your company’s network 
providers.
