I am installing a NEC DSX-40 and the Call Forward Off premises feature requires that "telco must provide Loop Disconnect Supervision" (pg 51 of DSX Software manual).
My Problem; the local telco customer rep and the sales rep both say "Huh?".
They are checking with engineering and I gave them what I think are other names for this (Calling Party Control, CPC Wink, Loop Current Disconnect Supervision) but I am wondering;

***What kinds of incoming lines will a DSX-40 support; loop start only?
I also think the lack of calling party disconnect might be causing a very long hang on auto-attendant/voice mail (1-2 minutes). I only saw it once though in a quick test.

***What kinds of disconnect supervision will the NEC DSX-40 support?

***Is there an industry standard type of loop start that I should be asking for?

BTW the local telco is Frontier, Rochester, NY.
Thanks,
GR

It will also be referred as disconnect order and supervise disconnect,

All phone systems with voice mail need something to tell them when the caller hangs up. Some one at the telco will know what this is. I have called to report this problem and told there is no such thing or I don't know what this is. When I hear that I hang up and call back until I get some one who does know.

Go to the customers site, call your office then have your your office hang up on you while you remain on the line. If the present phone phone system drops the line, you have disconnect supervision.

Also,

I would have the customer get centrex lines to do this; two reasons: 1- sound quality 2- with cetrex you will not be using 2 lines for every one forward, all lines will still be available for incoming and outgoing.

If your customer is geting voice mail, the voice mail supports "centrex transfer".

Be wary of Centrex, however, as most Centrex contracts will keep your customer locked in for a decade with heavy penalties to terminate early - at least if you are in the U.S.

Some customers also don't appreciate having to dial the additional 9 to get outside lines. You can bury one through the system on dial 9 for an outside line, but not if they are used to using direct line appearances.

Take a survey of how often they need to forward off-premises before considering the Centrex route. If it is a "must" used often, then Centrex may be a sensible solution. This is only IMHO.
