Chairman Pai Proposes Mandating STIR/SHAKEN To Combat Robocalls

In this case, “ebony phone” refers to the (usually) black housing of landline phones, either dial or manual that your parents probably used for years. Caller ID has long been supplied (for extra cost) to subscribers as a signal interspersed with the ring signal.

The answer to “what about ebony phones” is to require telcos to verify the Caller ID which is delivered to landline telephones along with the ring signal.

Again, this is not likely since it would impact the telco’s profit margin.
