Hi,
I've developed some iOS apps that target all Apple devices (iPhone, iPad, iPod) with all screen sizes. I also know UI issues with iOS 6, iOS 7, iOS8. I'm also experience with VoIP app (XMPP or Linphone), I would like to work for you on this project and next VoIP project.
Looking forward to working with you.
