I've got xfinity voice service. Called I.D. was functioning normally, and missed calls were added to the missed call list on my phone. I added NOMOROBO and the testing shows that it is enabled and configured correctly. However now only incoming calls from numbers in my phone's dialing directory show up on my caller ID display. All other incoming calls, whether blocked after 1 ring by NOMOROBO or not blocked show up as "Incoming Call" with no other caller ID information and non-blocked calls that are not answered are not added to the missed call list. Has anyone else experienced this or have any suggestions how to restore normal caller ID and missed call list behavior without disabling NOMOROBO?
