I had them in several houses over the years and don't think it was superseding technology that was the problem. Intercoms were: - kind of ugly and bulky - fixed in place - you needed to walk over to the panel and push a button to use; but now you're already by the door (where the panels were installed) and can probably just yell faster/easier - the person you're reaching might have volume turned down, so you resort to yelling anyway - you might be on the phone or taking a nap and would have to turn down to volume to avoid interruption - poor speaker/sound quality, so horrible for music playback - poor build quality and buttons/dials would regularly fail after 5 years or faster if used - finicky to setup with tons of manual tweaking required to get volume levels where desired - expensive to repair & proprietary - expensive to install
