Some telemarketer is using this number to mask the number they are calling from.  If you call the number back, there is a voice mail telling you this and they apologize for the confusion.

Scam telemarketer. Hang up.

Stop calling "scammer"!!!  You have been reported to the public utilities commission (puc)!!!!  You are going to prison!  My phone is being recorded for any further calls from you, 508-968-5630....
