Installing a Viking E 30 DoorBox. Ive got it on port 11 in 11-02 SLT. In 10-03 SLI its showing on port 3 as it should. In 32-02 when I add other stations for it to ring , I press the Doorbox and nothing happens. I delete the stations I added in 32-02 and still nothing happens.

Have you tried calling the doorbox from a phone set to make sure it's working? If you dial service code 702 then the doorbox number - you should be able to call it.
