Are you aware of the +878 "country" code and the UPT (Universal 
Personal Telecommunications) project?

http://www.visionng.org/index.htm
http://www.visionng.org/enum/Request_for_Temporary_Assignment_of_UPT_Numbers.pdf&e=7413

As an example, I can be reached on +878102843336600 which is 
available via an e164.arpa. ENUM lookup.  This is only now coming out 
of "beta" mode and into real production, but you may find it more 
reasonable to use a number range that has been correctly allocated 
rather than simply hijacking one that may in the future not be routed 
in ways that you expect or desire.
