Does anyone use RFC 3219 - Telephony Routing over IP (TRIP), or are there any vendors that implement it?

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. JT
