I had the HR20 installed on July 24th and had the Caller ID working great. Then on August 1st, it stopped working. I have not changed anything wi th the setup....I have checked my settings and all are as they should be... I have the upgrade.... 0x17e version..... Things seemed to work fine and now I do not get notifications....(yes they are turned on)..... Any thoughts? I know others have had issues as well.....the rest of the features are working well... Thanks PS..I also noticed when I do the system test, my phone does not "pass"....again, it had been working fine....and the phone line works great! Help!!!
