Hello,

I've purchased two Nortel BST Doorphones for my Norstar 4x16 system at the office. I was surprised how relatively easy it was to install them, following the manual. They are both working, I have set them up for two different chime types for the different doors.

However, one thing I cannot figure out is how to get multiple sets to ring indicating which doorbell is calling. In the Doorphone Admin Setup (F9*4) there is a "Call DN" entry, and it's currently set to 21 (main phone). If I set the rings to 1 or more, the DN 21 phone rings displaying which doorphone is calling, then sends a page chime on the entire system. I want multiple DN's to ring, namely 21, 22, 23, 26 & 31.

In the Doorphone manual there is a tidbit saying it can be done by programming "Answer DN's" on one phone, but I've no idea how to set that up. I've browsed the PDF file I have for my system (CICS 6.1 System Coordinator Guide.pdf) and I havent' been able to find anything about Answer DN's.

Any help would be greatly appreciated.
