We like ENUM. We support ENUM in our software. It works great for VoIP route discovery.
However, Simon has observed that inter-carrier route discovery coupled with interconnect price discovery could be useful for facilitating inter-carrier VoIP peering with settlement. We can't figure out how to do this with ENUM, so perhaps Simon's idea for DUNDi could be a solution.
