Tracing a call (MCID)

You can find out the origin of a call, in order for example to identify a malicious caller. You must apply to your local network provider for this feature. Your telephone must be configured accordingly, as otherwise the service will be rejected with the advisory message "Identification not possible".

You can use this function in the following situations:

During a call.

Call signal is heard, you lift the handset, the caller has already hung up. You have 20 seconds after the caller replaced the handset in which to initiate call tracing.

At the end of the call. The anonymous caller hangs up. You have 30 seconds in which to initiate call trac- ing.

On no account must you replace the handset until the identification is concluded.

You can initiate caller identification if you have pro- grammed a "Trace" function (page 42).

cLift the handset.
