Right. There are LOTS of ways. SPIRITS is one of them, but definitely 
not the only one. The information in the presence document exists 
across a bunch of different PSTN elements, including HLRs, VLRs, MSCs, 
  etc.

OK, I will add a reference in the next revision (assuming there is one).

I think the rpids "from" element would work well for that.
