Am on my third 625. All have caller id problems. Am getting only about 10% of received calls. Have tried all the usual fixes. Phone company checked line-ok. Have had dish 2004 to 2008, direct 2008 to 2009 and back to dish 625. All receivers have worked at that location except 625. Dish installed last 625 on 8-17-09. Caller id worked twice then quite. Installer left saying someone from his office would contact Dish and get back to me. 625 must have a problem, either hardware or software.
