Move logic of Call/Calling pages out of the page

[jordibc]

Murhaf, if you could remind me where we were putting the logic and an example of a module that is already using it?

@jordibc I suggest the about page example
But about page doesn't use a service, so you just need to add a service for calling page I guess

src
  calling
       calling.module.ts
       calling.ts
       calling.html
       calling.scss
       calling.service.ts

Thanks @MurhafSousli !

In case you chose ModalController, there is no need to make calling.ts as a lazy page anymore, it can be used as a normal component without calling.module.ts

src
  call
       calling-dialog
              calling.ts
              calling.html
              calling.scss

       call.ts
       call.html
       call.scss
       call.service.ts
