iOS Programing, making phone calls

Is it possible to make a call from my app without accessing the standart phone application?

The problem is that if I make a ca开发者_StackOverflowll, my app goes to the background, and I really do not need that. I need it to be always active even if I am calling.

No there is no way to do that, you can only make calls via de tel URL sheme.

You can use tel://123456789, but this will display a confirmation before opening the phone app.

There are a few apps, however, that open the phone app and make a call directly without displaying a confirmation (like Dialvetica).

To answer your question, no, you can not make calls directly from your app, unless you create your own version of Skype (the whole network, not just the app), and you probably don't have the time, money and resources to do that.
