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 xed 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 Specication 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.
