1.
An external call connects to an external number (either by transferring with Tandem Trunking or
by DISA caller).
2.
After 10 minutes (Tandem Trunking = PRG 24-02-07 or DISA = PRG 25-07-07), a warning tone is
heard and the user dials # (PRG 20-28-01) to extend the conversation.
3.
After three minutes (PRG 20-28-03), the warning tone is heard again. After 30 seconds (Tandem
Trunking = PRG 24-02-10 or DISA = PRG 25-07-08), the call is disconnected.
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
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
opposite side trunk. With an ISDN trunk, PRG 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
0
for an outside call (if allowed), the system routes the call via ARS.
• In a system with ARS disabled:
When a DISA caller dials
0
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,
automatically transferred Tandem Trunk calls, and DISA calls.
• Tandem Trunking also uses the Continue/Disconnect codes DISA uses.
• 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 (PRG 25-03 and PRG 25-04) are set to 104 (Speed Dial
Bin), the Speed dial is treated as an internal call no matter what PRG 13-01-01 is set to. If an
outside number is required, the trunk access code must be put into the speed dial bin.
• Park Retrieve is not supported using DISA.
