[enum-wg] Austria starts with the ENUM-based number range

Axelm,

For 1), Does it mean that in Austria, the session-control equipments (as you said,
the several components, and maybe including softswitch?) in Telco network all
support ENUM? 
For 2), Who possess(take charge in assigning) the 780 number range? Users should
have a 780 number first and then have a corresponding domain,yes?
For 3), I think the whole charge module can be refered to some aspects, not just
registry. For example, different ENUM services(call/Voicemail/conference..) can
have more charge module than '"per-delegation" based model'.
BTW,what kinds of ENUM services have been provided in Austria except call?

Best wishes!
Chenhui
