How to Make a Conference Call on an Android Phone. Conference calls are the staple of any team, remote or on-site. They’re quick and convenient for everyone involved, especially when there isn’t any screen sharing involved (and you don’t have the time to set up an elaborate video meeting).

There are tons of ways to set up conference calling, including using dial-ins from a landline. You probably already know about the dozens of conference call services out there, or already use the in-built conference calling feature in your uber-versatile mobile device. But that method has its limitations—we’ll go into that later. There’s a better way, and that’s the RingCentral app.
Unlike someone interrupting a conversation by making an incoming call, a conference call is one you set out to make intentionally: You make one call and then add a second call. Touch an icon on the phone’s touchscreen and then everyone is talking. Here’s how it works:
-
Phone the first person.
-
After the call connects and you complete a few pleasantries, touch the Add Call icon.
The Add Call icon is shown. After touching that icon, or a similar icon, the first person is put on hold.
-
Dial the second person.
You can use the dialpad or choose the second person from the phone’s address book or the recent calls log.
Say your pleasantries and inform the party that the call is about to be merged.
-
Touch the Merge or Merge Calls icon.
The two calls are now joined: The touchscreen says Conference Call, and the End Last Call icon appears. Everyone you’ve dialed can talk to and hear everyone else.
-
Touch the End Call icon to end the conference call.
All calls are disconnected.
