At Fall VON here in Boston Mark Spencer of Asterisk introduced a new concept for TN to URI resolution you might be interested in looking at.
Personally as with most peer to peer technologies you have some global scaling issues but he has expressed an interest in proposing the technology in the IETF.
Note he is explicitly NOT offering the draft in accordance with 2026
