[VoIP] ENUM Round Robin DNS?

[Jonathan Kay]

Question for Greg or anyone in the know.
I was wondering if it was possible to provide round robin ENUM lookup on 
the CNET servers?
 What I was pondering, was for service codes, like (in the UK)  8081 
Speaking clock, 100 Operator, 999 emergency  and so on.
By providing list of lookups to these codes (prefixed by 44 for UK, as 
normal) to load share around all * boxes offering the services for these 
codes. With no changes to their dial plan, callers would only need to 
dial the actual service code, rather than prefixing an office code each 
time. And we wouldn't be relying on one terminating * box, always being 
available.
