Early intel suggests these are charity calls for American Lung Assn. For years until last Spring Am-Lung had hired Akron call center InfoCision. Now they have appeared to switch to rival MDS Communications. Not sure if the deal is exclusive. The current crop of calls is about as bad as InfoCision's, with a similar style of calling repeatedly from a rotating set of numbers and often lacking any useful CID.
We've had calls for the past ten days from the following numbers which are likely on behalf of this charity: 202-367-9124
The calls from commercial fundraisers are exempt from Federal DNC under the charity status, even though such call centers are very much for-profit and pocket far too much of what these periodic campaigns collect. At times the "charity" group is itself a profit enterprise, compounding the deception. However, as a commercial entity, each commercial fundraiser is expected to honor its own no-call list and add any number upon request. Break that order, the FTC declares, and "the telemarketer may be subject to a fine of up to $16,000."
