Look at Apples Multipeer Connectivity framework. I have built an app that does exactly what you want. If you look to my profile and the questions I have asked you will get some good guidance. Though I recommend you do it with a backend since MultiPeer wasn't the best solution, atleast when it comes to supporting multiple peers and to be able to call another device that has the app in the background.

See Frank Shearar's Answer Here

In short, it looks like this would be a very difficult task.

Another option would be to use the Twilio SDK for iPhone (Obj-C). This would work well for what you're trying to do and would be a whole lot easier. Link
