I have a Sonic DSL line with phone service, with voicemail enabled. I have a fairly basic phone hooked up. It normally shows "NN new calls" on the screen if I've missed any calls (and lets me scroll through the caller ID info), and then I check voicemail online via member tools.
I've been getting calls from one source, or at least they always leave the exact same recorded message (some generic robocall -- "blah blah business credit blah blah"). I get a 31-second message, always the same, in my voicemail, but my phone never registers a missed call.
This isn't really a big deal -- just another robocaller -- but I'm curious why it's not showing up on caller ID on my phone.
If someone from Sonic sees this: my account is the same as my forum user name, and I left the most recent message in my voicemail -- from 352-353-xxxx (undoubtedly fake) on 2019 May 2.
I vaguely remember seeing news a while back that someone had figured out to game one of the big mobile phone company's voicemail systems, so that they could leave voicemail without ringing the phone. I guess some telemarketing scammer figured it might be 1% more likely to make them money or something. Any chance there's something similar going on here?
