I am trying to use call kit or another library to check when a user calls a certain number. I want to know when this happens so that I can send the user a notification. I know that you can detect incoming calls but not sure if outgoing calls are allowed. Is there any way for me to do this?
Thanks in advance

We are building a chat app using latest ejabberd and there is a use case where user A blocks user B. the requirement is to hide last seen or user's presence from each other. if A blocks B then its easy to hide these information from user A but how can user B be informed that user A has blocked them ? whats the best approach to tell user B the someone has blocked them on realtime while both are in a conversation , like whatsapp does now.
For presence, you do not have to use block, you can simply remove contacts from roster. That way, the other user is notified and can also stop sharing his presence.
There is XEP-0191: Simple Communications Blocking:

I think it will give you the answers you need. Now it depends how will you implement this functionality using chosen client library like Smack.
I have an ios app.
In which i have multi user account.So multiple user can Login.
When one user see other user profile and if that user is also online i want to notify him.
I can't get how to implement it.
If i have to continuously check some flag value on server if someone has checked their profile or how can i handle it?
Remote notifications is the way to do it. The logic on when and who has to be notified can be handled at the server.
You may have seen lots of apps asking for permissions to send notification. The downside being if the user denies that permission.
Polling from client side can also be one of the methods which can be used and but would require the client to do most of the computation.
So all in all, its a call you got to take considering what you are building.
I am not a developer as much as i am a project manager, i need to know more if the following is possible to help me decide the future of a project.
mainly my question is, can i trigger a certain method (function) in my application using the push notification ? so my app might be in the background (or not) and i want to send a push notification message that wakes the application and execute some piece of code.
if the answer is yes, can this be done without the user interaction ? so i mean without the user clicking on the push message ? to be some kind of automated, so i send the Push notification message, the iPhone receives it and execute the code, without the use interaction ?
i can set up my own APNS server if needed.
i am not looking for a code as much as i am looking for an answer if this can be done or not.
Thanks,
Yes, this is possible, as long as the user clicks on the notification. This could be done either with local notifications, or push notifications.
When an application is launched in response to a notification, the AppDelegate method application:didFinishLaunchingWithOptions: will have an option indicating the notification that precipitated the launch.
It cannot, to my knowledge, be achieved without user interaction.
In the process of building an operator application in C# I have encountered some problems. They all stem from the fact that the operator isn't actually a phone. So doing things like transfer a call (a BYE then REFER), or placing a call on hold (send another INVITE as a=recvonly) are easy for phones to do because they already hold state information about the call dialog from the initial handshake.
Is it possible to send INVITEs on behalf of another phone to get them into conference? Is it possible to send INVITEs on behalf of another phone to get them into hold?
Well, if you are using Asterisk I'd recommend looking into Asterisk Manager Interface and not deal with SIP protocol directly. It provides methods to create/transfer/hangup calls,monitor,etc, and everything else you might need.
Is it possible to have a background app display a notification based on who is contact details from an incoming caller, either before the call is answered or during?
No, the system will not allow you to interact with phone calls in any way.
You can set the image for certain people in the address book using the Address Book API. That way, a certain background image (potentially with a textual message) will be shown, based on who is calling.
With time, things change. Look at sync.me, when you get an incoming call, the latest post on facebook will show just above the accept/decline button. Though I still can't get the idea of how it is done.
