About 3-Way Calling (Conference Calling)
3-way calling works slightly differently on Swedish and U.S. systems.
Making a 3-Way Call in the U.S.
For U.S. configurations, follow these steps to make a conference call:
Step 1 Dial the first number.
Step 2 When the person you called answers, perform a “hook flash”; that is, hang up
quickly and pick up the phone quickly. This will put the first person you called on
hold and you will hear a dial tone.
Step 3 Dial the second person and speak normally when that person answers.
Step 4 To conference with both callers at the same time, perform a hook flash and press
3 on the telephone handset.
Step 5 To drop the second call, perform a hook flash.
Step 6 (Optional) To conference in additional callers, the last person called with a
Cisco ATA 186 can call an additional person, and so on. This is known as
“daisy-chaining.”
Making a 3-Way Call in Sweden
For Swedish configurations, follow these steps to make a conference call:
Step 1 Dial the first number.
Step 2 When the person you called answers, perform a “hook flash”; that is, hang up
quickly and pick up the phone quickly. This will put the first person you called on
hold and you will hear a dial tone.
