Can anyone suggest me is there a way to block all incoming calls for a while? or at least can I put my phone into silent pragmatically ? Please suggest
No. Simply you cannot do that. There is no public API is available to do that. Your app will be in sandbox mode. You cannot access them in anyway.
Now it can be done from iOS 10 and above using the CallKit framework upto a certain amount. The numbers we provide can be blocked. If you want to block all incoming calls, just use Airplane mode.
The CallKit framework provides programmatic access to VoIP functionality, as well as call blocking and identification.

Please let me clear, is it possible to integrate CallKit without using VOIP?
What I want to achieve is to get call history from iPhone. and I know it is not possible. So I want to create my own history with the help of CallKit. For this purpose I need following:
I want to detect incoming call (not voip)
Outgoing call (not voip)
In all states - background, foreground, not running, suspended
Call duration
Can we do this with the help of CallKit or is there any other workaround?
Note: It is not about VOIP Apps
is it possible to integrate CallKit without using VOIP?
I would say yes, SpeakerBox (the Apple CallKit example) doesn't use VoIP.
https://developer.apple.com/library/archive/samplecode/Speakerbox/Listings/Speakerbox_SpeakerboxCall_swift.html
is it possible to integrate CallKit in all states - background, foreground, not running, suspended without using VOIP?
No, if the app is suspended or not running you can't detect an incoming call.
For case of CallDuration in active mode can be traceable by using callkit. Let me know, if you are only interested to know Call Duration. I can give full detail.
Other all cases that you mentioned are not possible to trace, unless your phone is jailbroken.
How to block the incoming calls for a few minutes in iOS application?
In my iOS application I want to block the incoming calls when the user is attending the video interview. How can I achieve this?
Check the CallKit framework
The CallKit framework provides programmatic access to VoIP
functionality, as well as call blocking and identification.
Refer This Link : https://developer.apple.com/reference/callkit
It's clearly forbidden for a third-part app to block incoming
calls.However you can use CallKit to block unwanted calls. Your app
should be able to add blocked numbers.The reason Apple doesn't allow
you to block it is because there would be a lot of abuse and Malware
that would disturb user experience.
iOS doesn't let you generically block all calls coming in. in iOS 10 with CallKit, you can block specific numbers (documentation here), but you can't block all numbers for a given time
Firstly I am new to iOS development and I have extensively gone over the little documentation and tutorials there are of Apples CallKit framework, but I cannot figure out if this framework can actually block cellular calls or just VoIP calls?
The question is as simple as that, I need to know if CallKit can be used to block cellular calls, when I have predefined a list of telemarketers that use their mobile phones to call people in my country. I am just wondering if someone can give me a clear cut answer and then I could move on with my life, without having to waste more time, trying to get the CallKit to recognize incoming cellular calls.
Thanks!
Yes, you can block incoming calls using a CallKit extension
What exactly I need is that when an incoming call come and my app is in foreground than the call must be automatically received and loudspeaker must be activated.
I have seen many post in SO saying that to intercept the calls is not possible in iOS.
But what if I use any VoIP API and make calls from it to my app[app to app call] ?
can I receive the call automatically in that case or that time also the SDK won't allow me to do so as its the core part of iOS I am too much confused.
This is not possible with UIKit, and furthermore if you did use private Apis your app would not be approved.
How does Truecaller intercept incoming phonecalls on the iphone to display caller ID?
I didn't think this was possible from within the app?
Specifically, if I wanted to build this functionality, what protocols would I go about using?
http://www.truecaller.com/how-it-works
On an iPhone, without jailbreaking it:
- you cannot intercept a call in any way
- you cannot determine the phone number nor the caller ID identifying information regarding the call. Even if you could there
is no way to alter what is displayed on the call screen
- you cannot block the call
- your program can get a notification when a call is being made/terminated etc. But only if your app is executing in the
foreground at the time of the call or if the app is in the
background and has a relevant background mode (even then you can
only know there is a call in some circumstance, depending upon what
you're doing in the background and what state your in etc. Its too complex to describe the exact situation here briefly)
True Caller doesn't do that on iOS as it isn't supported with the native SDK. See their FAQ:
http://www.truecaller.com/support , specifically the "Why don't I receive live caller ID?" Section under "iPhone/Windows Phone". If you must though, try looking into a solution for jailbroken devices.
It's impossible to "intercept" calls. It is possible to handle the "background event call" when a iPhone get's a call. That said, Truecaller doesn't intercept calls. More info can be found on their website.
