0401 - Transfer Recall
0403 - Call Fwd Ring No Answer
Call rings extension A for the Transfer Recall 
time.
Call transferred to extension A, which is the sin-
gle member of a type 3 hunt group that is set up 
to hunt to extension B.
In unanswered at extension A, the call hunts to 
extension B which is the single member to a type 
5 UCD group that is set up to overflow to exten-
sion C.
Extension B
The call now rings extension B for the Call 
Forward Ring No Answer time.
0403 - Call Fwd Ring No Answer
If a UCD group member does not become free, 
the call diverts to the programmed overflow desti-
nation.
If still unanswered, the call diverts to Key Ring
Busy UCD
MasterIn unanswered at extension B, the call 
camps-on to the busy UCD master exten-
sion number.
0401 - ACD/UCD Overflow
The call camps-on to the UCD group for the 
ACD/UCD Overflow interval, waiting for a mem-
ber to become free. (Note that the Call Coverage 
Delay timer also starts now. See Call Coverage 
Keys on page 61 for more.)

The call the rings the overflow destination 
for the Call Forward Ring No Answer time.

Programming List
Circular Hunting
Program 0401 - Transfer Recall (page 455)
Set how long a trunk call waits at a busy member extension. This interval also sets how long a 
call rings each member extension as it cycles through the group.
Program 0401 - DIL No Answer (page 456)
Set how long a DIL rings its destination member extension before cycling through the group.
Program 0403 - Call Forward Ring No Answer (page 466)
Set how long a call rings an idle UCD Hunting group member before cycling to the next 
extension in the group.
Program 1807 - Hunt Type (page 554)
Enter the same hunt type for all extensions in the Circular Hunting group. The available hunt 
types are: 1 (Ring No Answer Trunk), 2 (Busy/Ring No Answer Trunk), 3 (Busy/Ring No 
Answer All Calls), and 4 (Busy Trunk)
Program 1807 - Hunt Destination (page 554)
For each extension, enter the next extension in the hunt group. Be sure the last extension 
points back to the first extension.
Refer to the table below for a Circular Hunting programming example.
Circular Hunting Programming (for 301, 303 and 304)
1807: Hunt TypeEnter the same Hunt Type for all three extensions:
1 = Ring No Answer Trunk
2 = Busy/Ring No Answer Trunk
3 = Busy/Ring No Answer All Calls
4 = Busy Trunk
1807: Hunt Destination
301303
303304
0403 - Hold Recall
0401 - Trunk Revert
If not picked up, trunk call recalls the extension 
that put it on Hold after the Hold Recall time.
Hunt group member puts trunk call on Hold.
The call then rings the extension that put it on 
Hold for the Trunk Revert time.
If still unanswered, call diverts to Key Ring

DS1000/2000 Software ManualChapter 1: Features167
Terminal Hunting 
Program 0401 - Transfer Recall (page 455)
Set how long a trunk call waits at a busy member extension. This interval also sets how long a 
call rings each member extension as it cycles through the group.
Program 0401 - DIL No Answer (page 456)
Set how long a DIL rings its destination member extension before cycling through the group.
Program 1807 - Hunt Type (page 554)
Enter the same hunt type for all extensions in the Terminal Hunting group, except for the last 
extension. The last extension should have hunting undefined (by pressing CLEAR).The avail-
able hunt types are: 1 (Ring No Answer Trunk), 2 (Busy/Ring No Answer Trunk), 3 (Busy/
Ring No Answer All Calls), and 4 (Busy Trunk)
Program 1807 - Hunt Destination (page 554)
For each extension except for the last extension, enter the next extension in the hunt group. 
Be sure the destination for the last extension is undefined (by pressing CLEAR).
Refer to the table below for a Terminal Hunting programming example.
UCD Hunting
Program 0401 - ACD/UCD Overflow (page 457)
This timer sets when UCD overflow occurs. When all UCD agents are busy, a queued call 
rings for this interval and then overflows to the destination set in Program 0510 - Overflow 
Destination (page 485). 304301
(This causes hunting to loop back to 301)
0401: Transfer Recall TimeThis timer sets how long a trunk call waits at a busy member 
extension. It also sets how long a call rings each member 
extension as it cycles through the group.
0401: DIL No Answer TimeThis timer sets how long a DIL rings its destination member 
extension before cycling through the group.
Terminal Hunting Programming (for 301 and 303)
1807: Hunt TypeEnter the same Hunt Type for all three extensions:

(Hunting stops at 304.)
0401: Transfer Recall TimeThis timer sets how long a trunk call waits at a busy member 
extension. It also sets how long a call rings each member 
extension as it cycles through the group.

Program 0510 - Hunt Group Master Number (page 485)
Define the master extension number for the UCD hunt group. UCD Hunting group master 
numbers can be 100-299, 332-400, or 417-899. They cannot be in the extension (300-395 in 
DS2000 or 300-325 in DS1000) or trunk (401-448 in DS2000 or 401-406 in DS1000) number 
range. By default, the systems uses codes beginning with 0 for operator access and 9 for 
trunk/trunk group access.
Program 0510 - Overflow Destination (page 485)
Define the overflow destination for the UCD hunt group. When all UCD group members are 
busy, calls the to master number ring the overflow destination instead.
Program 1807 - Hunt Type (page 554)
Enter hunt type 05 for all extensions in the UCD Hunting group.
Program 1807 - Hunt Destination (page 554)
For each extension in the UCD Hunting group, enter the master number defined in Program 
0510 - Hunt Group Master Number (page 485).
Refer to the table below for a UCD Hunting programming example.
Other Related Features
Call Coverage Keys (page 61)
A keyset can have Call Coverage keys for UCD Group master numbers.
Call Forwarding (page 65)
If a member of a Circular or Terminal Hunting group forwards their calls, hunting will follow 
Call Forwarding. If a member of a UCD Hunting group forwards their calls, calls to the exten-
sion follow forwarding but calls to the UCD master number do not.
Direct Inward Line (page 118)
DILs to a Circular or Terminal Hunting group member initiate hunting. In addition, DILs to a 
UCD master number ring the UCD group directly.
Directory Dialing (page 143)
Intercom Directory Dialing will show UCD Group names.
Do Not Disturb (page 146)
Placing an agent in DND temporarily removes it from the UCD group.
Flexible Numbering Plan (page 172)
UCD Hunting group master numbers can be 100-299, 332-400, or 417-899. They cannot be in 
the extension (300-395 in DS2000 or 300-325 in DS1000) or trunk (401-448 in DS2000 or 
401-406 in DS1000) number range. By default, the systems uses codes beginning with 0 for 
operator access and 9 for trunk/trunk group access.
Group Ring (page 183)
Group Ring calls do not activate hunting.
Intercom (page 227)
Voice-announced Intercom calls do not initiate hunting.
UCD Hunting Programming (for 301, 303 and 304 with master 750)
0510: Hunt Group Master 
NumberSelect UCD Group 2 and assign master number 750.
0510: UCD Overflow Destina-
tionEnter 305
1807: Hunt TypeEnter the Hunt Type 5 for all three extensions.
1807: Hunt Master NumberEnter 750 for all three extensions.
0401: UCD Overflow TimerThis timer sets when UCD overflow occurs. When all UCD 
agents are busy, a queued call rings for this interval and then 
overflows to the destination set in Program 0510 - Over-
flow Destination (page 485).

DS1000/2000 Software ManualChapter 1: Features169
Transfer (page 393)
Trunk calls transferred to a Terminal or Circular Hunting group member activate hunting. In 
addition, trunk calls transferred to a UCD group master number activate hunting.
Voice Mail (page 414)
To set up extension overflow to Voice Mail:
- In Program 1807 -  
Hunt Type on page 554, enter Hunt Type 3.
- In Program 1807 -  
Hunt Destination on page 554, designate the Voice Mail master number as 
the Hunt Destination.
Unanswered calls, in addition to calls to the extension while it is busy or in DND, route the the 
extension’s mailbox.
For Terminal and Circular Hunting, unsupervised transfers (UTRF) from the Voice Mail Auto-
mated Attendant route like trunk calls. Supervised transfers (TRF) from the Voice Mail Auto-
mated Attendant route like Intercom calls. In either case, unanswered calls eventually route the 
initially called extension’s mailbox.
