• If a Transfer Recall is not answered before the Recall Duration Timer expires, the call will revert 
to the Attendant group.
• If the called party does not exist, the call recalls to the transferring extension.
• You cannot transfer a call to an extension that has Do-Not-Disturb (DND) activated.

extension 225.
• Calls can be transferred from paging using supervised transfer.
• If a call is unsupervised transferred to a busy extension, the call will camp on to the busy 
extension.
• To transfer to a outside party, it is best to use supervised transfer. If the trunk-to-trunk on-hook 
transfer restriction is enabled, a blind transfer will result in the loss of the second call but the 
second call will be kept on hold. If not enabled and the second outside party is busy, the 
transferred party will receive busy.
Camp-On (Call Waiting)
Description
If you dial a busy extension, you can camp onto that extension and send a Call Waiting signal to the 
called party. The called party then needs only to replace the handset and pick it up again to be 
automatically connected to the new call. The called party can also press the HOLD key to place the 
first call on hold and then answer the waiting call.
The System provides two types of call waiting: 
•Automatic Call Waiting: You do not need to enter a code to send the Call Waiting signal to 
the busy extension. You need only to remain on the line. 
•Manual Call Waiting: You must enter a code to send a Call Waiting signal to the busy 
extension.

Conference Calls
Description
Conference Calls allow you to add another party to an existing conversation. With the standard 
system configuration, up to 4 parties can be included in a conference call at any one time. If the 
optional Conference Card is installed, additional parties up to a total of 8 can participate in a 
conference call. 
Any combination of extensions and CO lines can be in the conference as long as the original 
extension is in the conference and the total number of parties does not exceed 8. Only one operation is 
used to establish and add to a conference. You simply have to place the current call on hold, dial the 
next party and press the CONF key. No different operation or access code is required to add 
additional parties to the call.
When no optional conference card is installed, the system supports the following types of four-party 
conference calls:
•4 extensions
•3 extensions and 1 CO line
•2 extension and 2 CO lines
• 1 extension and 3 CO linesAction Result

Operation
See Section 750 - Key Phone User Guide for operating instructions.
Hardware Requirements
• A Conference Card (VB-44120) must be installed in the System in order to conference more than 
four parties.
Related Programming
• FF1-0-03: Extension COS (8-Party Conference)
• FF1-0-03: Extension COS (Unsupervised Conference Call)
• FF1-0-01: Splash Tone (3-party conference)
• FF1-1-04: Conference Hold Call Recall Timer
• FF3: Extension COS
Considerations
• If all the internal parties hang up, the conference call will be disconnected. If the internal party 
remains in the conversation, the conference call remains in progress.
•When three or four parties are conferenced, a built-in 4-party conference circuit is used. If no 
4-party conference circuit is available, a conference cannot be established.
•When a fifth party is added, the conference is moved to a conference circuit on the 8-party 
conference card. If an 8-party conference circuit is not available, a fifth party cannot be added to 
a conference.
• Once an 8-party conference circuit is used, it continues to be used as long as the conference 
continues.
• An 8-party conference card supports up to four 8-party conference circuits. However, the card 
must be placed in cabinet slots 1, 5, or 9 to support more than one 8-party conference circuit (and 
jumpered accordingly).
•During a conference call hold, the held conference members cannot use the HOLD key. Pressing 
the key has no effect.
•Conference Hold is an Exclusive Hold (only the conference originator can retrieve the 
conference).
•Conference Hold cannot be transferred.
Do-Not-Disturb
Description
You can make an extension unavailable by activating the Do-Not-Disturb (DND) feature. When DND 
is activated, calls to that extension receive busy tone.
You can set or cancel DND from either your extension or from an alternate extension.

•Voice Calling: Extension calls are connected immediately, without a ringing tone.

extension is voice or tone calling. Regardless of the default, you can toggle between voice or tone 
calling by entering the Tone-Voice Call feature code. For example, if the extension default is tone 
calling, you can make a voice call to another extension by entering the Tone-Voice Call feature access 
code.
