MALICIOUS CALL TRACING, MCT

If you are disturbed by malicious external incoming calls,

you can request a number tracing from the network provider.

You can invoke MCT during or after an ongoing

conversation. The external line can be held for a limited

period of time.

Order During an ongoing conversation:

Press

Dial tone.

3 9

Press

The system acknowledges with different tones whether the

MCT request was accepted or rejected.

DIRECT INWARD SYSTEM ACCESS (DISA)

(Optional) If you are assigned to use this function and you are working

externally, you can call your office and get access to an exter-

nal line in order to make business calls. The business call will

be charged your office extension number or an account num-

ber. You will just be charged for the call to the office.

The external telephone must be of push button type provided

with a hash (#) and star (*) key or a mobile telephone

adapted for dial tone pulses (DTMF).

After a completed DISA call you must hang up before a new

DISA call can be made.

Depending on the type of authorization code and if an

account code is used, different procedures must be used:
