Then again, I don't get calls very often, so may be I have more patience with calls. Emails? I am probably much less diligent about determining their authenticity.
An sms is so much simpler.
[1] Oddly, on my last phone, with T-mobile, disabling voice mail wasn't possible through their internet account management. I did manage to get my voice mail disabled, but I had to call them and complain until they agreed to disable it.
I was forced to implement this after I started getting several junk calls a day. I don't think I've has a single junk call ring through since I put it in place. Rarely one will leave a prerecorded message. Interestingly, from looking at my call logs the frequency of junk call attempts has also dropped to just a couple a week after about a year with this is place.
Another nice thing about Anveo: their voicemail transcription mostly works compared to the comedy that is Google Voice's transcription.
Fortunately, I came to the opposite (and correct) conclusion, seeing as how I had received the call 30 seconds after attempting to use my Chase card for a large international purchase online and was able to quickly get that issue sorted. Still, it seems to current state-of-the-art that the rest of the bank is not aware of the phone numbers used by their fraud departments.
Searching for that phone number will (if it's legit) likely point to a contact page on the bank's website.
I really wish that more companies would back the robo dialers with real people who can actually listen/respond to the outgoing message. There's some standards to detect voicemail vs. an actual response, just the same nothing replaces real people with a working mind. For a while I had my outgoing message prefixed with the disconnected tone. That was a fun way of getting off of call lists.
