Matrix SETU VFXTH System Manual 204
Call Transfer - Blind
Blind Transfer is when you transfer the call to the desired party, without informing the party of the transfer.
SETU VFXTH enables the transferor to know the result of the transfer activity, i.e. whether the call has been
transferred successfully or not. As soon as the transferror dials the Blind Call Transfer access code, SETU VFXTH
loads the Transfer Notification Timer. This timer stops if the transferor goes On-hook. SETU VFXTH indicates to the
transferor of the result of the transfer activity within this Timer. The Transfer Notification Timer is configurable.
This is how Blind Call Transfer works:
• A (transferor) is in speech with B (transferee). A wants to transfer B's (transferee) call to C (transfer target),
without informing C.
• A dials Flash (or Call Hold access code) to put B on hold and then dials Blind Call Transfer access code.
• A dials the number of C and B's call is transferred to C.
Now, to know the result of the Blind call transfer, A should remain Off-hook after dialing C's number. One of the
following results may occur:
• If transfer is successful, A (transferor) gets confirmation tone for the duration of the Confirmation Tone
Timer, followed by error tone for the duration of the Error Tone Timer, followed by system standby.
• If the transfer target C is busy, A (transferor) gets busy tone, and speech is established between A and the
transferee B.
• If no message is received during the Transfer Notification Timer, A (transferor) gets error tone for Error
Tone Timer, followed by system standby.
Blind Call Transfer is not allowed if you dial the Blind Transfer access code after putting the remote held
call on hold.

To use this feature, you must enable Blind Transfer in the Class of Service of the FXS Port. Call Hold must also
be enabled in the Class of Service. For instructions on enabling features in the Class of Service of the FXS Port,

If required, you may change the duration of the Transfer Notification Timer. The range of this timer is 001 to 999
seconds. By default it is set to 60 seconds. To change the duration of this timer, go to “System Parameters”.
