The caller ID feature does not work on our 625 DVR. We have tried everything. A tech support person has been out to look at the DVR and is clueless. Phone jack is ok, we have enabled the caller ID feature, and DVR works fine. We have a hd receiver and a 311 receiver also. The caller ID works on both receivers. I think it has to do with the wiring. Does anyone have a suggestion. Thanks!
