I have a Norther Modular ICS

I am looking to get caller ID to work on some phones that do not normaly ring.
The user would do a "pick up" to answer the line. I tried to do a feature 811 prior, but it did not work (I assume it needs to ring first). Any thoughts?

Also
With the phone system in night service.
An outside caller who call in gets the auto attendant. The outside caller then dials the users extention. The users then dials feature 811 but they do not see the call ID information. Any thoughts?
