[Asterisk-Users] RDNIS

[Michael B. Murdock]

Fortunatly we are a supplier to the "mighty powerful telco" so we can often
get them to dig deep to get the implementation right... Unfortunately, doe
to the complesities of the Class-5 switches they often don't know where to
look to enable a feature and either you help them out (by becoming a switch
expert yourself) or trust that the support they are getting from the switch
vendor is accurate (and in this case it does not appear to be so).
