Transfer Busy timer expires. Then, if the call is not answered, it recalls the called endpoint’s
Attendant. If the called endpoint is forwarded, the call follows the programmed forwarding
path.
When a hunt group pilot number receives a call through DISA, the call rings or circulates
according to how the hunt group is programmed (i.e., linear or distributed).
If a caller dials a valid hunt group pilot number that has no members assigned to it, the call
automatically rings at the primary Attendant endpoint until the Abandoned Call timer expires.
If the call is not answered before the Abandoned Call timer expires, the call is disconnected.
Security Codes
DISA trunks can be assigned security codes (up to eight digits in length) that are required for
access to the system. The installer can program separate codes for each DISA trunk group to be
used during day and/or night modes.
During database programming, the programmer can determine the number of times that a
caller may unsuccessfully attempt to enter a security code and/or dial an extension number. If
the user does not succeed within the determined number of attempts, the call will be discon-
nected (if the security code is invalid) or transferred to the primary Attendant (if the extension
number is invalid).
Using DISA
To use DISA:
1. From a DTMF endpoint, dial the phone number of the DISA trunk. When the call is
answered by the system, you hear system intercom dial tone.
If you hear a single progress tone, enter the appropriate (day or night) DISA security
code, followed by pound (#).
2. Dial an extension number or a hunt group pilot number. (To call the primary Attendant,
dial 0.) You hear music or ringing until the call is answered.

DISA Example
NOTE
To prevent unauthorized access to the outgoing trunks, all trunk groups using
DISA should have a security code.
NOTE
If DTMF decoders are unavailable when a DISA call is received, the incoming
DISA call is automatically sent to the primary Attendant.
