[enum-wg] ENUM for SMS?

Right .. totally closed carrier only. Its all about SS7
avoidance/destruction. The use of carrier (private) ENUM data queries
interconnection for voice and other realtime communications is coming but
there are some technical issues and CAPEX problems among the carriers that
are inhibiting deployment. It's a substutiion play for Global Title
Translation in part. SS7 cannot handle new IP services .. DUH!

The GSM association has been looking into this for some time as the
signaling infrastructure for the IPX and now there are several international
landline operators that are looking at private ENUM architectures as well
lead by FT/Orange. Of course there are lots of private companies deploying
this as well like Xconnect in the UK. 

The problem has been getting some of the suppliers to properly support 3761,
though that is very very quickly changing.

IMHO this is going to get even bigger as the EC is looking to mandate full
database Number Portability across Europe during the next term of the
Commission. Vivian Reading has sent out huge noises on this recently. ENUM
technology is perfect for this in carrier networks. 

I've heard rumors that even in Japan there is increasing interest in this.
Onward Routing for LNP in Japan is driving NTT crazy as their all IP
infrastructure is progressing and the Japanese LNP solution for mobile is
not that great either.
