I just downloaded the E911 compliance software and "newer" tech bulletin. Panasonic tech support passed me up the line, into the never ending hold music, to confirm actual compliance to this law. First level would not commit to the legal status of the update. That tech bulletin is identical to what I have.

I am very curious about the continuation of the product using this PATCH. After 50 minutes on hold, like in the old days, I feel like I am on my own on this. After 45 years, it is Time to retire, for sure....
