Obviously they have been making calls for years. One of their current names is "AMVETS CDSI" that is the name of a multi-branched, twisted group of supposed charities claiming to help Vets. The calls are to solicit donations of clothes, etc. to be sold at their thrift store.

They used to use women calling from their home phones. Looks like they have moved up to full illegal telemarketers (calling for a charity does not exempt you from the DNC list).

Other names they use:
