 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 CBX 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 CBX.

After the caller has hung up, listen for the dial 
tone.

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