Hello Treggers,
I need to establish a list of all features available to Primary Rate ISDN
users on the public network.  
Currently I am interested in features that relate to voice usage and not
necessarily data usage, 
and at this point,
I'm not necessarily interested in interoperability issues that can arise
between providers for a given feature. 

Can anyone out there point me to a source(s) where I can compile a list for:
1.      North America, 
2.      Europe (Euro ISDN), and
3.      Japan (ISDN 1500) 

Thanks
