Ed,

Thanks for the quick reply. One detail I left out ( might not change much..) = We have a direct fiber to the Long Distance Carrier's POP, and they told us they will transmit "whatever
we send them".

Doesn't this mean our PBX is( technically ) in the same position
as a service provider's switch?

But if no PBX can actually send a Caller ID Name, then even that wouldn't matter...

Anyway, Thanks for the info...
