My mother in law used a device you press a button for a medical emergency.
I believe the company that runs this service sells your name or is the originator of this call.
Someone should investigate these First Alert companies.
I think they are using the numbers from their sick and old customers.
I received a call from 385-744-7413 that showed on caller ID as "Invalid number". As always on numbers I do not recognize, I let it go to voicemail. When I did an internet search, one of them said "385-744" from Pakistan. My phone showed that the caller left a voicemail. When I logged in, it turned out to be a telemarketer pedaling "medical emergency" devices. I deleted and added the number to my "Caller Block" list. BTW, when I highlight "Call Type" as Telemarketer here, I am unable to get this page to accept that. So I'll post this with the "Call Type" as unknown.
