1. A method comprising:

  • receiving, at a computing device, for a first call, placed from a first party at a first communications device, to an intended second party at an address associated with a second communications device, data representing call audio received at the first communications device during the first call;

    determining, by the computing device, based on the data representing the call audio received at the first communications device, a first provenance fingerprint indicative of one or more communications devices participating in the first call with the first communications device;

    determining, by the computing device, based on the first provenance fingerprint, that a third communications device is likely participating in the first call from the first party at the first communications device, the third communications device being a different communications device from the first and second communication devices; and

    responsive to the determining that the third communications device is likely participating in the first call, outputting an indication that a different communications device from the first and second communications devices is likely participating in the first call.
