Anyone have an ENUM trunk set-up?

I was so close to having ENUM done until Verizon sued VONAGE for patent infringement. One patent that was violated was looking up a record in a database (aka DNS aka ENUM) and retrieving a route to deliver the call. Until this patent gets revoked for prior art (patent filed in 2001 and DNS dates back to the 70s when darpa used it); I am going to hold off on ENUM development. Anyone using ENUM on trixbox in a reselling capacity is toying with having their whole operation closed down via a 50million dollar patent infringement lawsuit by verizon.

btw ENUM is different than e164 and there is a private PSTN version of enum as well as the open enum project.

I would love to work on ENUM, just as soon as Verizon either abandons this rediculous patent or files an exclusion for ENUM lookups :)
