they tried sending me a fax (that's what the beeping you hear is) but my machine was down so it went to phone. caller id showen private so i'm sure its sales junk or BS.
I received an illegal fax from an illegal pharmacy, totaldrugmart.com, which is offering to smuggle drugs into the US from overseas. (They admit in their FAQ that it isn't legal for people in the US to order from them, yet they are spamming fax numbers in the US.)
They claim to be a Canadian pharmacy, but they just process orders there. They may actually just send your prescription to some pharmacy in a third country to have them ship you drugs that have not been approved for sale in either the US or Canada.
The 856 phone number may be spoofed. Report the fax spam to their hosting service at http://www.netnation.com/
