BST Doorphone, can't call across network?

[NYSBAPhone]

I have 5 BCMs, set up with 3 digit DN's. Dialing a "7" prior to DN will get you to any other BCM, (working over fiber/approx 80 miles between furthest sites).
When using BST doorphone, I cannot figure how to get it to dial out to another system, (group or DN, etc...) About a year ago, I tried working with our vendor, (Verizon) who, after calling Nortel were told that it couldn't be done. Well, I am again revisiting this, can anyone help, or has anyone ever gotten the BST to talk across the network to another BCM on the system? If so, HOW??! We are currently using a Viking phone on a POTS line, but that is problematic due to copper quality issues in the area of the Doorphone.

Any and all help is appreciated.

Reading through the manual seems to imply this is not possible. I assume you have already tried setting Prime Line for the doorphone DN to the line pool you want to dial out of (whichever pool dest code '7' is tied to) and then setting Call DN to the target DN on the remote system (omitting the '7' dest code).

I found this interesting thread in the archives:

Apparently, even if you set the doorphone's Call DN to a local handset that is configured to allow redirect and then has call-forward (Feature-4) set to a remote extension, it will not work: the doorphone will drop the connection when the local set it's configured to call initiates the redirect! One clever workaround that someone came up with in that thread (Norstarguy's post @ 6 Sep 07 10:25) was to set the Call DN on the doorphone to an ATA DN, loop the ATA back into the KSU on an available analog trunk line, add that trunk line as a line appearance on an available handset, and then configure that handset for redirection and set its call-forward (Feature-4) to the remote DN. Quite a hassle just to get this working!

It was hypothesized at the end of the thread that Nortel specifically engineered the doorphone to disallow having its calls be redirected "off-net" for security reasons: if it could be configured to either send a call over a trunk port OR allow a call from itself to be redirected to a trunk port, some employee could in theory have the call be redirected to a mobile phone, and then use that to gain unlawful entry to the protected facility after-hours.

NathanA, thanks for your response. Indeed, when I tried the redirect on a local phone, I could see the call drop almost instantly once the redirect started... (watching BCM monitor)
THanks!

In short?
If the Viking was using and an ATA then have the Door phone ring that same ATA?
If the Viking was using a trunk then wire an ATA to that trunk and have the Door phone ring the ATA.

Hi, curlycord. Actually, I have the Viking(s) working on POTS lines, independent of the BCMs.
