We are all getting bombarded from Robocalls, many coming from China.
With the China scam, they are hoping to get Chinese speakers telling them they owe the Chinese government thousands of dollars and need to pay it asap or action will be taken against them and their families.

Then there is Neighbor spoofing. This is where the area code & first 3 digits in many cases are similar to yours.

If you answer to any of these, ensure that you are not recorded saying the word "yes" as the recording will be used to authorize them to charge credit cards, etc.
DNC really just stops legitimate telemarketers from calling you. Those spoofing, etc. are outside the country and functioning outside the law.
On my mobile I use Hiya.
Home phone was nomorobo, but instead blocked ALL numbers except those I input (tons of calls from China).
Office has not been touched.
The other crime here is minutes are still a thing with many mobile phones, so in effect this is stealing $$$ from many.
The major telecoms should be able to verify a call coming in (this preventing spoofs) but unclear on what laws prevent them from verifying numbers.
Like email spam, all we can do is minimize its annoyance.
