CID100 Error

CID100 Error

I have called Comcast twice and contacted chat support twice but so far have not gotten this issue fixed. When I select the iTV option on my TV/cable box and select Caller ID and set it up when I exit I get a CID100 error.  Initially I was told the Caller ID option was not on my account but now it is.  The consistent response is let me reset your cable box, wait 4-6 hours, and it should be fixed.  Problem is on 2 separate TV/Cable boxes.  My main cable box is the Comcast Cisco RNG200.  Caller ID on my phone works fine and it is the Comcast phone service.  I do have a technician coming out to my house tomorrow but I would like to get this resolved myself.  I know the problem can't be with the cable box as I have 2 different cable boxes and both display the CID100 error when I try to setup Caller ID,  Additionally, I tried setting up caller id on my PC and that does not work either.

Re: CID100 Error

Did the tech that came out fix the problem. My box is doing the same.
