CORDLESS PHONE FOR MX-ONE™

17.7 Direct Inward System Access (DISA)
If you are assigned to use the DISA function, you can work from outside
the office network and still have all your outgoing business calls charged
to your office extension number or an account number.
You will only be charged for the call you have to make to the office in
order to get access to an external line through the office network.
Note: The external phone must be of push button type provided with the
keys # and *, or a mobile phone adapted for dial tone pulses
(DTMF).
You have to initiate DISA for every individual business call you make.
This means that you have to terminate a DISA call before you can make
a new DISA call. The procedure varies depending on which authoriza-
tion and account codes you use, see below.
