Making a Conference Call in Sweden
Procedure
Step 1
Dial the first number.
Step 2
When the person you called answers, press the flash or receiver button on the phone handset. This will
put the first person you called on hold and a dial tone will sound.
Step 3
Dial the second person and speak normally when that person answers.
Step 4
Perform a hook flash, then press
2
on your phone keypad to return to the first person. You can continue
to switch back and forth between the two callers.
Step 5
To conference with both callers at the same time, perform a hook flash, then press
3
on the phone keypad.
Once you conference all three callers, the only way to drop a caller is for that caller to hang up.
Step 6
(Optional) To conference in additional callers, the last person called with a ATA 187 can call an
additional person, that new person can call someone else, and so on. This is known as “daisy-chaining.”
Call Waiting in the United States
If someone calls you while you are speaking on the phone, you can answer by performing a hook flash.
You cannot conference in all three callers, but the first person you called could call someone else and
daisy-chain them into the conference.
Call Waiting in Sweden
If someone calls you while you are speaking on the phone, you can answer by performing a hook flash
then pressing
2
on your phone keypad, or you can conference them with the person to whom you are
already speaking by performing a hook flash then pressing
3
. You can also perform a hook flash then
press
3
later during the call to create a conference call.
Performing a hook flash then pressing
1
hangs up the first caller and answers the second call. If there is
no answer after one minute, the caller receives three beeps and a busy signal.
To enable call waiting for Sweden, go to the ATA 187 phone configuration page and select the value for
Call Sequence as
Bellcore FSK
.
Note
In ETSI mode, the user must pick up the call waiting rather than start the conference service. The user
cannot trigger the call conference service directly, when there is a call waiting.
About Call Forwarding
In SIP, the ATA 187 can control call forwarding and call return.The type of call forwarding that is
supported for the ATA 187 is Forward Unconditional—Forwards every call that comes in.
