As you all know, Siri is whacked with the Prius. I've been using Hey Siri with some success but today I found a great solution that I am quite happy with. One Prime Day, Amazon offered an Echo Auto for $19.99 so I thought what they heck and bought one. I thought if it works, great. If not, then I would return it. I setup the Echo Auto and it took about 5 minutes. Now I can say "Alexa, call (whomever)" and it looks it up on my phone and makes the call. No more "hangups" before connecting the call. Yes, I realize it is another piece of tech but I thought I would share. The other benefit is that I can easily access all my music libraries and other Amazon stuff. Hope this helps someone out there that struggles with the Siri "hang up" issue.
