As an author,

I acknowledge that the draft should be clear, and somehow, contradicts 
itself. What the draft tries to say is what Andrew just pointed out: if 
the endpoint is not aware of its E.164 address, but just that there is a 
Circuit-Switched connection, then the c line should be:

  c=PSTN - -
