title: How to use VoIP in iOS
body: <p>I have to build a mobile App (iOS)  for people with Dementia. When they get lost, they start the App and there will be a simple HELP Button for them. When they pressed this Button, the App will build a connection with someone from their family, who can help them. The “Supervisor” can see 2 Cameras - Front + Back Camera view of the Caller + his Location on Map.</p>
  
  <p>Is it possible to make this App? It's my University Project. Could someone give me some tips on how can I make this App step by step - things like this VoIP Connection and so on? I would really appreciate it because I have no idea where to start. I have already made some Apps for iOS but I have never worked with things like VoIP</p>
  
  <p>Thanks!</p>
