I've had NOMOROBO for a few weeks now and it hasn't blocked a single call. I report the numbers to NOMOROBO; some of them are repeat offenders, but it doesn't seem to help. I'm grateful that Cox provides this service but so far it hasn't done anything to block robocallers. Just venting.
Same problem here. I even checked the NOMOROBO data base and found numbers on their hit list that were still coming thru weeks after they had been marked. and I have twice verified with NOMOROBO that the service is active on my Cox landline
ps- have yet to hear the phone ring only once
Hi Sattamander, here is some additional information about how the nomorobo system works, https://bit.ly/2KhHvrg. Are you able to access your profile on nomorobo.com, and see if it's activated on the website? The simultaneous ring can be active in your Cox profile, however, if it is not activated through the actual website itself, the service will not function. -Kevin M. Cox Support Forum Moderator
