Acme Packet did at one point, perhaps they still do?  Jasomi also used  
to have a TRIP stack - maybe remnants of that still exist somewhere in  
Ditech.  There was an open-source reference implementation from Vovida  
that didn't really work (I put some funding into it a while back, but  
the task was too big to complete.)

It's a nice idea, but there are serious political issues to overcome  
to make it work inter-organization which is why I suspect it never  
really took off.  That, and the concept of "routing" in this fashion  
is so unusual to standard telephony-type engineersmthat it just didn't  
get mindshare.

The good news is that it created/validaed the concept of the ITAD (IP  
Telephony Administrative Domain) as a number similar to that of an  
ASN.  This is being used in the freenum.org ISN-style dialing methods.
