Return to application after call is cancelled

Question

I want to use telprompt:// scheme to return to my application after it makes a call. But I have a problem.

If remote person is busy two buttons are shown to me: Redial and Cancel. So if I press Cancel I won't return to my application. Is there any way to handle it?

P. S. Isn't telprompt:// in Private API?

Answer 1

Here You can Use the WebView and Load Request on it.

 UIWebView *callWebview = [[UIWebView alloc] init];   
 NSURL *telURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel://%@", phoneNumber]
 [callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];

I am Sure It would work with Charm.....

I think you need:

[[UIApplication sharedApplication] openURL: [NSURL URLWithString:[NSString stringWithFormat:@"telprompt:%@",num]]];
