Here's all I have:

programs:

7-1 assign DPH card
1-7-00 assign doorphone to port
4-03 & 4-04 assign doorphone ringing day/night to digital ext's
Doorphone ring to analog devices is NOT supported (including analog adpaters)
1-7-04 doorphone ring type

DPH (4 ) u10 supports 4 devices

Doorphones 1 & 3 share a speechpath as do 2 & 4


Good Luck

It's actually easy to setup, and the DP's cross connect on every other pair
