I had the same problem, a call from AthenaHealth that was an attempted fax.
It's not a telemarketer. Your number has been mis-dialed in their automated faxing system by accident. Call them at 800.981.5084 and wait for the "other call" option. A live person will pick up (during business hours). Tell them your issue (nicely, please, it's not the operator's fault) and they will remove the call from their system. When I called, it was removed within an hour.
