I used to work in healthcare network/telecom and then as a healthcare network/telecom VAR before working at a networking manufacturer currently for the last ~year. The below may be slightly out of date, and I was just the person getting told by the lawyers instead of the one with the real understanding, but it was what I'd run into at the time for the US.

The understanding I always got from legal was "it's continually the company's legal liability under the RAY BAUM's Act whether the address is correct when the user dials 911 on/via the corporate systems, not the user's". Sometimes the conversation sounded like you could potentially have users sign something to transfer that liability, other times legal didn't seem to even want to entertain the idea as valid. Regardless, none of the companies ever ended up wanting to go that route for either concern of general friction/overhead or concern there would be employees pushing back that they don't want to sign it and instead would just want 911 to work (which is also a reasonable position for an employee to want to hold). I.e. implementing automatic VOIP location for some users but not others was either impossible on some systems or just seen as a nightmare to try to track/audit, even if they were willing to try to make every employee perfectly happy about it. A bit of a legally induced quagmire for a good intent (accurate 911 not being something a place could opt out of providing) which had trade offs in reality.

RAY BAUM's compliance requirements for for nomadic endpoints in went active in 2022 but most companies had already started trying to be compliant a little prior to that when fixed endpoints needed it anyways. Some companies of course don't bother, either knowingly or unknowingly assuming that compliance risk. Before that it wasn't really a topic.
