Yes I have made sure that I'm receiving caller id. To test my theory I did the following: I put a DTH-16LD-1 phone in the warehouse. I did a delayed DIT to ext 200 (Station 13). I enabled CO4 ring on the DTH-16LD and left it disabled on all other phones. When I do a test call to CO4 I get a ring on station 12 (the DTH-16LD phone) with caller ID. Ten seconds later CO4 DIT's to ext 200 and the caller ID is dropped. In addition, I've enabled ring on Station 13 (ext 200) for CO4. So when I call CO4 I get a ring on the DTH phone and the analog phones. Again the DTH shows the Caller ID and the analog phones do not. When the call times out it goes to the mailbox for ext 200 as it was DIT'ed, which is what we want.

Any further suggestions. I'm all ears!!!!
