Direct Inward System Access (DISA)
Outside callers with touch tone telephones can call in to lines programmed for Direct
Inward System Access (DISA) and dial an extension or outgoing line without going
through an attendant or operator. See your System Administrator for details.
1. From outside the system, dial the public telephone number assigned to DISA. The
call will be answered and you will hear system dial tone.
If you do not dial within 10 seconds, the line disconnects.
2. When you hear dial tone, dial an extension or an outside line.
3. If you dial an outside destination, you may need to enter a security code provided
to you by the System Administrator. When you hear the tone, enter the security code.
If accepted, the call will proceed.
4. If you receive busy tone and you want to dial another number while the station is
still ringing, press
