Three-way calling + +
If your telephone service includes three-way calling, the Supercom
4400 three-way calling feature lets you put one call on hold, call
another number, and carry on a conversation among three people.
Follow these steps to use the three-way calling feature:
1. Call the first number and begin your conversation.
2. Place the first person on hold by pressing the key, the
key and the key ( + + ).
You will see HOOK FLASH on the display followed by
TYPE NAME, NUM, OR CR.
3. Dial the second number and begin your conversation.
4. Press + + to reconnect to the first person. You now
have a three-way calling conversation.
If the second number is busy, press + + to reconnect with
the first person.
You must have three-way calling service from your
telephone company to use this feature.
Note: If someone calls you to set up a three-way conversation, you
should press + + to be sure that you are using Baudot
(45) code. You may have originally connected in Turbo Code and all
three people in a three-way conversation must be using Baudot (45)
code.
