Why is U-verse Call Blocking limited to 20 numbers?
This has been a busy season for scam calls, spoofed calls, and telemarketers who ignore the Do Not Call list. After switching to U-verse Voice from AT&T POTS I was pleased that Call Blocking is an included feature, but the limit of 20 numbers is unfortunate.
Just today we got three scam calls; the "Your PC is infected" scam, a fake IRS "You are being sued" call, and a caller claiming to be our health insurance provider trying to collect personal info. At this rate, clearly 20 numbers is not enough.
My mobile phone offers a Call Blocking feature. I can block unlimited numbers. I can block by pattern, which is useful because often the scam calls come from fake exchanges like 805-117-xxxx and I know (having worked in the telco industry) that 1xx is not a real exchange. On my mobile I simply enter "805-1*-*" or "805-1xx-xxxx" as the pattern and calls from that fake exchange are rejected. In fact I can reject any call from a 1xx exchange as "xxx-1xx-xxxx".
Does anyone know why U-verse Voice limits this feature to 20 numbers? My mobile phone is obviously less powerful that AT&T's servers, so it's not a processing power issue.
