By doing that you turn this from a source identity non-repudiation
capability to 
a routing assurance capability (receipt non-repudiation).

Despite being useful, I thought that was not in scope.

I would not necessarily restrict it to the "called party".  This is the
dominant use case we've been discussing, I.e that I receive a call and want
to be as certain as possible about the identity of the endpoint calling me.

However, I could be calling out to my customers or clients and as the
"calling party" would like to be as certain as possible that I am reaching
the correct endpoint.  Consider a bank wanting to reach a customer about
issues with the customer's account - or to verify a recent transaction. Or a
doctor's office want to relay results to a patient and wanting to be sure
they are reaching the patient's number.

My understanding is that we are aiming to solve the "secure origin
identification" challenge - and that could apply to either or both ends of
the conversation.
