Direct Inward System Access (DISA)
Aspire Software Manual Features ◆297
Notes:
●While the outside caller is setting the function via DISA, no one can use the
extension which is being set.
●The outsider caller can not set/cancel a function via DISA when the selected
extension is being used except during incoming ringing (including incoming
ACD calls). If the extension is busy, the call will be terminated.
●The VRS is required to send the fixed messages heard during the feature setup.
Conditions
(A.) The DISA caller must use a 2500 type (DTMF) telephone. DISA is compatible with calling
devices that meet the DTMF signaling requirements of EIA Specification RS-464. DISA
trunks must be ground start or supervised loop start.
(B.) The Continue/Disconnect code must be DTMF.
(C.) With an analog trunk, the Continue/Disconnect code may work using DTMF sounds from the
opposite side trunk. With an ISDN trunk, Program 14-01-25 must be enabled to detect the
Continue/Disconnect code.
(D.) The Continue/Disconnect code is not accepted while dialing a trunk.
(E.) Continue/Disconnect codes will not work if all DTMF receivers are busy.
(F.) When used with the Networking feature, both systems must be programmed the same.
Default Setting
Disabled.
