Call Transfer

Calls can be transferred to another station or CO Line.

Calls can be transferred by either the screened or unscreened method, or be directly transfer

red to a voice mailbox:

• Screened Transfers: Allows the user to announce a call to the destination station before

completing the transfer.

• Unscreend Transfer: Allows the user to complete a transfer without announcing the party

to the destination station.

• Also see "Transferring Calls Using an SLT Phone" on page 1-183.

2. If the transferring station does not answer, the Attendant station receives a ring back

for the amount of time set for Attendant Recall timer.

3. If none of the stations answer within the allotted times, the call will be dropped.

• Detect Loop Lost or Disconnection must be available for detection by CO lines.

• If the transferred CO Line does not have answer information (analog CO), and the

transferred call is not answered, the call does not ring back to the transferring phone; the

call is disconnected after the Unsupervised Conference timer expires.

Transfer Hold Recall time expires. The line is then released.

• During a screened transfer, pressing the original incoming CO Line button while making a

transfer to an external number completely disconnects the call (incoming and outgoing).
