Hi all,
I have a 3300 that has incorporated a door entry system. This is connected via an analog trunk port (ONS) with the built in ports.
The trunk is programmed via the trunk attributes to dial a group of phones. When the door entry button is pressed however no ringing is evident. The door entry installers say that the single pair is generating the voltage for the phones to ring but nothing is heard.
I created a trunk group which seized the analog port and when the door entry is pressed and the trunk seized you have communication across the trunk.
I have changed parameters in the CO Trunk Circuit Descriptor including Ringing Expected amongst others but nothing seems to be working.

I have also tried to connect the door entry to an analog extension on hotline to the group but that does not work either.
Has anyone else ever come across difficulties with this? Any help would be much appreciated.
