We like to request:
That you can make your own choice from a file beside the use of a caller snapshot (fallback video display)
a extra talk back-button that will hold the talk-back line open, you will have to push it again to release
Thanks very much. I just want to mention that you might find it useful to know that you can replace the default 'test card' image and use that, if all you want is a single custom fall-back image. For more extensive image options, such as individual contact images, I agree more flexible options are highly desirable.
