Hello. Can't find out if daemon application can be run on non-jailbroken iPhone. And what is Apple policy about this stuff? I don't really know if my idea is possible at all... I wonder if it's possible to create such a daemon that can intercept outcoming user call and play custom tone signal while remote user does not answer our call. Almost all cell-operators provides a service of custom call tones which means you can listen to some music while waiting for response... This drives me wild.

Plain and simple: It's not allowed.

No; Apple doesn't allow daemon processes. Since iOS 4, it allows apps to go into the background when you push the home button, but that's really just a form off application switching. The app can't do very much while in the background.

Apple allows only a limited set of background tasks. They are:
- Background audio
- Voice over IP
- Background location
- Push notifications
- Local notifications
- Task finishing
More details can be found in the iOS developer site. Note, also, that they won't work on an iPhone 3G.
Per your update:

No, it's not. Apps cannot interact with calls in any way. Incoming and outgoing calls suspend execution of all other apps.
