Correct incumbent teleco carriers do not like ENUM for the obvious 
reasons that is not unique to Portugal :-)

Ah not really New Telecos especially Cable operators entering the VoIP 
space want to avoid paying termination and compensation to the incumbent 
for calls. They wish to engage in IP to IP end to end calling and a 
"bill and keep" economic model of interconnection. Consequently have a 
very serious rationale for using ENUM in some form Public, Private or 
Infrastructure.

That is certainly the emerging model in the US and in the EC. We're 
seening lots of activity on that front in US CA NL AT etc.

Think about interconnecting enterprise PBX's.

Early results from Austria and the EC indicate its a long adoption cycle 
yes.

It depends on how much you charge. Free trees are not e164.apra we have 
designed the namespace to maximize its authority and integrity. But you 
cant charge too much for registrations.

Well part of the problem is the scale of the tree and the US and Canada 
have been part of that problem. The EC countries have been way ahead of 
us in North America on the adoption curve but now that 1.e164.arpa will 
come on line soon and Japan and Korea etc there is reason to believe 
some critical mass will begin to accelerate adoption.
