• “DISA1” or “DISA 2”must be assigned to exchange line(s) as the exchange line mode in
programs [414] through [416].
• After the DISA Delayed Answer Time assigned in program [504] expires and a ringback
tone is returned to the caller, a DISA call will be answered. The caller can dial during the
message or after the tone.
• This system can store up to 10 programmable DISA built-in auto attendant numbers in
program [501]. Each number is 1 digit.
• The DISA built-in auto attendant number may be the same as the first digit of other
numbers (extension number,etc.). To avoid confusion, the system waits for the second
digit for a preprogrammed amount of time in program [517] (default: 2 seconds). If the
timer expires, the system will assume that the first digit is a DISA built-in auto attendant
number.
