The posibility to start a Phone Call on your phone outside of the app would be awesome. Clients who just dont want to use LC or Twilio and just want an more efficient way to copy the number to their normal "Phone App" on their phone would be absolutely perfect. It is already possible to Copy the number, change manually to the phone app, paste it and start dialing, but I think being able to choose your internal "phone app" as the standard dialer would be an absolute game changer for small businesses and could be a real efficency boost in working with the app. Would absolutely push the usability of the app.
