Call from Colorado - answered and hear intermittent horn blowing. I get calls like this all the time. Cannot understand the purpose of these calls and what could possibly be accomplished by making them.
Hate to reply to myself - but wanted to add that I have 40 numbers saved with "Horns Blowing" as the contact name. The sound is not a fax machine sound. The horns are identical from every single number.
They actually are "fax spammers" trying to send you junk faxes. To get removed from that one call 855 405 2898 and just for preventative reasons these are 2 others like it that I know of... 844 872 4274 and 877 469 6456. Hope this helps!
