Direct Inward System Access
Outside callers with touch tone phones 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 CTX System Administrator for more
details.
1. From outside the system, dial the public telephone number assigned to DISA. The
call is answered and you hear CTX 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 CTX System Administrator. When you hear the tone, enter the
security code. If accepted, the call proceeds.
4. If you receive busy tone and you want to dial another number while the station is
still ringing, press and repeat Step 2.
Do Not Disturb
If your station is in Do Not Disturb (DND) mode, internal, external and transferred
calls do not ring your station and Off-hook Call Announce calls are denied. You can
continue to make calls while in the DND mode. When originating a call in DND
mode, you will hear a short burst of interrupted dial tone followed by continuous dial
tone. You can start dialing at any time during either tone.
If you put your Primary extension into DND mode, all calls to that telephone are
rejected. If your extension is set for Call Forward-Busy or Call Forward-Busy/No
Answer, the call is redirected to the forwarding destination immediately.
If you put an extension other than the Primary extension into DND, only calls to that
extension on your phone will be blocked. Appearances of that extension on other
telephones continue to ring.
