Setting Up Transfer Recalls for Idle and Busy Extensions
The system allows extension users to transfer calls from their extensions to other extensions, while maintaining the
privacy of the connection.
This means that calls can be routed to DX-120 system destinations (extensions, UCD
groups, virtual numbers, etc.) in such a way that the wrong party cannot easily intercept them.
• There are two types of transfer you may use:
- Screened/Supervised transfer
Supervised transfer means that before the transfer is completed, the system announces the call to the
destination extension. This transfer method allows the transferring party to transfer the call to another
extension if the destination extension cannot take the call.
- Unscreened/Unsupervised transfer
Unsupervised transfer means that the system simply delivers the call to the destination, regardless of the
destination’s readiness to accept the call.
• When extension users complete a transfer the system places the outside line on exclusive hold.
The call can then be retrieved only at the extension user’s telephone or the telephone where they transferred the
call.
• Calls that are transferred are subject to a unique transfer recall time.
• When transferred calls go unanswered at the destination, the system recalls (rings) the call to the transferring
party when this timer expires.
• There are two recall timers that affect transferred calls:
- Transfer-Busy Recall Time
- Transfer-Idle Recall Time
• Idle and Busy represent the status of the destination extension during unsupervised transfers.
- If the destination extension is busy, the system uses the Transfer-Busy Recall Timer.
- If the extension destination is idle, the system uses the Transfer-Idle Recall Timer.
• The following conditions apply to setting the transfer recall time.
- Extension users can transfer CO line calls and intercom calls.
- The system places transferred CO lines that recall on system hold.
- When transferring CO line recalls, the system displays the line number and extension number from where the
call was transferred.
- The transferred party will hear ring-back tone while the call is transfer ringing.
- In a screened transfer, if the destination extension answers the intercom call in voice announce hands-free
mode and does not go off hook, the system rings the destination extension.
- In screened transfer, if the destination extension answers the intercom call by lifting the handset, the system
immediately connects the caller to the destination extension.
- The system does not direct recalls to the programmed Alternate Attendant extension.
• Other features whose programming may be affected by transfer recall time include the following:
- Transfer and Answer Call
- Recall
- Call Forward
- Forced Intercom Tone Ring
- Call Park / Call Park Answer
