This number called a Federal Gov't line. No answer on the other end...Silence... I tried calling it back and it said that this number is out of service... Phone company should be responsible for these number where they can call out and annoy people But people can not call that line and but the crap out of them .... What a money grab on the phone company's part.
Caller IDs can be spoofed ... faked ... forged.
The phone company is not liable for those crimes.
The phone company does not "grab money" from those criminals.
However, YOU can bear some responsibility, and report or block specified phone numbers!
If you are indeed a Federal government worker, you should be aware of those facts.
