How can I make a conference call / three-way call on my iPhone?
Some iPhone users don't realize the ability to make multi-party phone calls is built right into the iPhone software. To initiate a conference call check out the following steps:
1. Make a normal phone call.
2. Touch the Add Call button to make another call. The person you're already on the line with will be put on hold.
3. After speaking to the second person, touch Merge Calls. You now have a three-way conference call where all parties can hear each other.
4. Repeat steps 2 and 3 to add more people. Up to 5 calls can be merged depending on your carrier.
To add an incoming call:
When the new call comes in, touch Hold Call + Answer. Touch Merge Calls to join the newcomer to the group.
To hang up on one caller:
Touch the Conference button and touch the red phone icon next to the call you want to drop. Then select End Call.
To talk privately with one caller:
Touch the Conference button, then select Private next to a caller. You are now speaking to one person. To resume the conference touch Merge Calls.
