Conditions
•
The DISA caller must use an analog (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.
•
The Continue/Disconnect code must be DTMF.
•
With an analog trunk, the Continue/Disconnect code may work using DTMF sounds from the oppo-
site side trunk. With an ISDN trunk, Program 14-01-25 must be enabled to detect the Continue/
Disconnect code.
•
The Continue/Disconnect code is not accepted while dialing a trunk.
•
Continue/Disconnect codes do not work if all DTMF receivers are busy.
•
When used with the Networking feature, both systems must be programmed the same.
•
In a system with ARS enabled:
When a DISA caller dials
9
for an outside call (if allowed), the system routes the call via ARS.
•
In a system with ARS disabled:
When a DISA caller dials
9
for an outside call (if allowed), the system uses the routes programmed
for Trunk Group Routing.
•
Transferred calls on DISA, DID, DIL, ISDN trunks, or from the VRS can display the reason a call is
being transferred (Call Forward, Busy, No Answer or DND).
•
Long conversation cutoff is controlled separately for manually transferred Tandem Trunk calls, auto-
matically transferred Tandem Trunk calls, and DISA calls.
•
Tandem Trunking also uses the Continue/Disconnect codes DISA uses.
•
Department Calling with Overflow Message requires PZ-VM21 for VRS.
•
DISA can only be set to call forward to another extension. Call Forward Off-Premise is not supported.
•
When the DISA/VRS Ring Group Transfer (Programs 25-03 and 25-04) are set to 104 (Speed Dial
Bin), the Speed dial is treated as an internal call no matter what Program 13-01-01 is set to. If an out-
side number is required, the trunk access code must be put into the speed dial bin.
