Blind and Attended Call Transfer
BT200 supports both blind and attended call transfer. Each is easy to use. Use blind transfer if you want
to transfer a call without speaking with someone first; use attended transfer if you want to speak with the
xxxxxxxx prior to transferring call.
Blind Transfer - Transfer an active
call to a third party without announcement.
Press the TRANSFER button and wait for a dial tone. Dial the third party’s phone number followed by the
SEND button.
Expected outcomes:
a) A quick confirmation tone
(call waiting tone) followed by a dial tone. This indicates the transfer is
successful. Hang up or place another call.
b) A quick busy tone
followed by a restored call (on supported platforms only). The busy tone
indicates the transfer failed.
c) Continuous busy tone
. The phone call has timed out. NOTE: continuous busy tone does not
indicate the transfer has been successful, nor does it indicate the transfer has failed. It often
means there was a failure to receive second NOTIFY – check firmware for most recent release.
NOTE: The “Enable Call Feature” must be configured to “Yes” in the web configuration page to enable
this feature.
Attended Transfer - Transfer an active
call to a third party with an accompanying message. User has
the option to speak to the intended receiver of call prior to transferring the call.
Press the FLASH button for a second dial tone. Dial the third party’s phone number and press the SEND
button. If the call is answered, press TRANSFER to complete the transfer and hang up. If the call is not
answered, press FLASH to resume the original call.
NOTE: If Attended Transfer fails, and party A hangs up, the HandTone-496 will ring party A to remind A
that party B is still on the line. Party A can pick up the phone to resume conversation with party B.
3-way Conference
The BT200 supports the advanced 3-way conferencing feature. To use 3-way conferencing, assume
Caller A and Caller B wish to conference Caller C.
1. Press CONFERENCE for dial-tone, placing Caller B on hold. Dial third number and press SEND.
2. Press CONFERENCE again to establish 3-way conference call.
3. If Caller C does not answer, press FLASH to resume conversation with Caller B.
NOTE: If either Caller B or Caller C drops the call, the two remaining parties can still talk. However, if
Caller A (conference initiator) ends the call, the conference is terminated and all lines hang up.
Retrieving Messages
The blinking red MWI (Message Waiting Indicator) indicates a message is waiting. Press the MSG button
to retrieve the message. An IVR will prompt the user through the message retrieval menu.
Mute/Delete
1. To enable/disable mute during a call, press MUTE/DEL button.
2. To delete entries when dialing, press MUTE/DEL to delete the digit.
3. To send a call directly to voicemail (without picking up the call), press MUTE/DEL
