While on a call on iPhone
When you’re on a call in the Phone app , you can switch the audio to a speakerphone or Bluetooth device. If you get another incoming call, you can respond or ignore it.

In the bottom row from left to right are the add call, FaceTime, and contacts buttons.](https://help.apple.com/assets/5C913108094622D50F674514/5C91310A094622D50F67451E/en_US/6996f1c99b6f5ae7929c4e1687219c39.png)
Adjust the audio during a call
Change the volume: Press the volume buttons on the side of iPhone.
Mute: Tap the mute button.
Put the call on hold: Touch and hold the mute button.
Talk handsfree: Tap the speaker button to switch to the speakerphone, or tap the audio button to switch to a connected Bluetooth device.
Use another app while on a call
Go to the Home screen, then open the app.
To return to the call, tap the green bar at the top of the screen.
Respond to a second call on the same line
If you’re on a call and receive a second call on the same line, do one the following:
Ignore the call and send it to voicemail: Tap Ignore.
End the first call and answer the new one: When using a GSM network, tap End + Accept. With a CDMA network, tap End and when the second call rings back, tap Accept, or drag the slider if iPhone is locked.
Put the first call on hold and answer the new one: Tap Hold + Accept.
With a call on hold, tap Swap to switch between calls, or tap Merge Calls to talk with both parties at once. See Start a conference call.
Note: With CDMA, you can’t switch between calls if the second call was outgoing, but you can merge the calls. You can’t merge calls if the second call was incoming. If you end the second call or the merged call, both calls are terminated.
Note: On models with Dual SIM, when you’re on a phone call, any incoming calls on your other line go directly to voicemail (if available from your carrier); you won’t receive missed call notifications.
If you set up conditional call forwarding (if available from your carrier) from one line to another when a line is busy or not in service, the calls don’t go to voicemail; contact your carrier for setup information.
Start a conference call
With GSM, you can set up a conference call with up to five people (depending on your carrier).
Note: Conference calls may not be available if your call is using VoLTE (Voice over LTE) or Wi-Fi calling.
While on a call, tap Add Call, make another call, then Tap Merge Calls.
Repeat to add more people to the conference.
During the conference call, do any of the following:
Talk privately with one person: Tap
, then tap Private next to the person. Tap Merge Calls to resume the conference.
Add an incoming caller on the same line: Tap Hold Call + Answer, then tap Merge Calls.
Drop one person: Tap
next to a person, then tap End.
