Just had whole home D* installed last week consisting of 1 HR24-100 and 3 H25-700 receivers and the new black BB Deca. Very strange problem with caller id. When using telephone I get a "incoming call- Unavailable-Unavailable" message on my screen even though there is NO call coming in. This keeps popping up every 10 seconds until I hang up the phone. This is happening on 2 Tv's only and I've narrowed it to two rooms that share a splitter where my Deca is installed. The other two tv's are fine. I have tried switching cables around on splitter to no avail. Finally I disconnected the Deca from the splitter and all CID problems went away and CID works normal on these two tv's again. So it's a problem obviously with the Deca hooked to the splitter for these 2 rooms. Anyone have ANY idea what is causing this? It's driving me nuts! If you need any add'l info I will be glad to provide. I am hooking the Deca back up so I can access VOD and unplugging phone lines on those two tv's for now till I get answers. Thanks in advance for any help out there!
