So can any please help me to avoid this ISD call Indian local call..

Answer 1

The telprompt wants the number in the international format. So you need to convert it to that. I think for India and the number you are trying to call, this should be +911800000002.

So this should work:

NSURL *phoneURL = [NSURL URLWithString:@"telprompt://+911800000002"];
if ([[UIApplication sharedApplication] canOpenURL:phoneURL]) {
    [[UIApplication sharedApplication] openURL:phoneURL];
} else {
    // handle that case. e.g show number to user so that they can
    // type it in a phone manually or copy it to the clipboard and
    // notify user about that.
}

Depending on how the local numbers compared to international format works in India, you might need to remove the 1 on your number, not sure about that.

On a sidenote: You should always use the international format when dealing with phone numbers. Otherwise a device that is currently outside of the destination country may call somebody else or simply can't place the call at all.
