[Asterisk-Users] CPC, Calling Party Control, Disconnect supervision, -- how to tell that to Verizon (east coast)?

[Andrei (MPI)]

Hello,

I would be grateful if anybody could tell me what I should tell Verizon 
in NJ so they would enable "disconnect supervision" for my lines.

Apparently "remote hangup notification" or "disconnect supervision" or 
"calling party control" is NOT the magic phrase for them. Although 
disconnect supervision is in the glossary on their website.

Thanks a lot in advance.
Andrei
