Chapter 3 Managing Linksys IP Phones
Using Call Features
Once the conference starts, the 900 Series phone plays a special brief tone to all three parties to indicate that a conference call is in progress. The initiator of the conference call can terminate it at any time by hanging up. The initiator can leave the conference without ending the call by pressing the join soft key; this allows the other two parties to continue the call. This is implemented as a call transfer, which may not work if the other two parties are hosted by different service providers.
If the extension is configured with an external Conference Bridge URL, the conference is not limited to three participants; it can include as many as the conference bridge supports. There are two restrictions that apply when using an external conference bridge:
•The conference can only be initiated (by pressing the conf soft key) when the third party has answered, instead of when the phone is either ringing or answered
•Ringing call cannot be brought into a conference by pressing the confLx soft key; only calls that are on hold can be brought into the conference with the confLx soft key.
Attended Call Transfer
An attended call transfer allows a user to optionally transfer a call to a third party, after having a discussion with that third party. There are two ways to perform an attended call transfer:
•During an active call, press the xfer soft key to place the current call on hold and to activate an idle line key.
•Dial the transfer target number on the newly activated line. When the target is either ringing or answered, press the xfer soft key again to complete the transfer.
While one or more call appearances is on hold, initiate a call on an idle line key. While the call is either ringing or is connected, press the xferLx line key. If only one other call is on hold, the active call is connected with the call on hold. Otherwise, you are prompted to select to which line key to transfer the call.
At the completion of call transfer operation, the holding call peer is the transferee, and the connected or proceeding call peer is the transfer target. The case where a call transfer is completed when the transfer target is ringing is called a
Blind Call Transfer
A blind call transfer allows you to transfer a call without speaking with the receiver of the transferred call. For the user, the call ends as soon as the transfer target phone number is dialed. The user phone sends the contact information for the transfer target to the phone of the other party on the call. The information is carried in a signaling message. When the message is sent, the user phone is dropped from the call and the other party phone automatically dials the transfer target.
To perform a blind call transfer, press the bxfer soft key and then dial the target number. The bxfer soft key automatically becomes active during a call, but it may not be visible on the display. If the bxfer key is not visible, press the left/right arrows on the Navigation button until it scrolls onto the display.
Some SPA phones do not have bxfer soft keys. To perform a blind transfer on these devices, during the call, press the xfer soft key, or the line key of an unused line. There must be a spare line available to perform the transfer. Once the new dial tone is heard, enter *98. The phone prompts the user to enter the phone number of the transfer target. Enter the number to complete the blind transfer. If the user phone has more than one call
