Can I dim or mute the iOS notifications during a Zoiper call?

Question

During a Zoiper call on my iPhone the notifications (new email etc) are very loud.

Is there a way to dim or mute (with vibrate still on perhaps) the notification sounds during a Zoiper call?

Answer 1

Due to restrictions from Apple for the third party application, Zoiper cannot change the behaviour of other application on iOS. Especially the system ones.
