New iOS upgrade in time to time, User interface Screen easier compare to older iOS version. Most helpful changes made Apple in recent iOS 9 are calling screen, Home app screen layout, Settings app and many more. Even 3D touch is more powerful and useful hardware functionality for to do long operation with ease. That will save your time or conjunction as well. Here I experienced about how we can manage call screen like iPhone call hold, Call to forward, and Create Group or conference Audio/ Video call from iOS 9 or later updated iOS version.
Steps for iPhone call hold, forward to another call or Make conference call
When you dial number from dial pad with blue round call button, Next screen Show up all calling options on process call screen. In that case mute or hold call option use at any time on start a call or in-between call period.
Note: Hold call option on screen available for FaceTime audio/ Video or on Carrier call.
More Very useful options are: Mute call (Your voice can’t at another side), Speaker (Listen loudly incoming voice to you), Search contacts in contact app, Add member for group or Conference call tap on ‘+’ icon.
See the Facetime call iPhone Screen
Carrier call iPhone screen
Here, meaning of hold call is only mute your sound from your end, Not save minutes used for whole call. So, don’t wait for long time, Make call again is the best option in place of iPhone Call hold or Mute.
