How to keep mute button available during call

I use my iPhone for conference calls regularly, with a Bluetooth headset/microphone. Often I keep my mic muted except for when I speak.

It is awkward that when I want to speak, I need to wake-up and unlock my phone, before pressing the mute button.

Is there a way to make my phone stay awake during calls, without changing the sleep/lock settings generally?

Solution 1:

Swipe right at the unlock screen during an active call and the controls are displayed. There's no need to unlock the phone to access the mute.

Solution 2:

In iOS10 you can just tap the number + call duration in the lock screen and it'll bring up the phone controls.

Solution 3:

I've found a really easy way. If your phone is locked, simply click the phone number/contact name and it quick links you to the screen with the mute button on.

Like another poster, I've found when you unlock the phone normally, it links you to the last app, and then you've got to app switch to go to the phone and then mute, so it's unlock->app->switch->mute.

The method above is click->mute.

It's not perfect, but it's meant I don't have to have an uncomfortable 5 second pause when someone wants to speak to me and I've muted my sound.
