Is there an app that allows an iPhone-to-iPhone local network call with shared music? My wife and I started going to a gym recently.  We each have our own separate workouts and we listen to music through our earbuds.  We realized though that this has reduced our evening chat time, so I had this idea to "call" each other to idly (verbally) chat during our separate workouts at the gym.  And I was wondering if it was possible for us to listen to the same music as we chat.  I've tried a bunch of different searches, but the best I can figure is that we can make an actual phone call and listen to our own separate music.  We have unlimited plans, so that's a possibility, but I think it would really be nice if we were listening to the same music (with independent volume control, i.e. voice versus music).  Is there an app that will do this, ideally just over a local network (as opposed to making a call that routes through a cell phone tower or some internet service)?
Short answer no. I found a link to an article that explains this.


  Playing music or any other audio while on a phone call is easy:
  
  While on an active phone call, tap the Home button to get to the home
  screen Open the Music app, find any song or podcast, and press play
  Return to the phone call screen by tapping the green titlebar Music
  (or any audio) plays immediately, but instead of outputting through
  the external speakers, it will be played through the ear speaker. This
  prevents the music from being piped through to the other end of the
  phone, and that means the other end will never know you’re jamming to
  Milli Vanilli to make it through their tortuously boring phone calls
  and wait times.
