I just got my 7232 box, and I am trying to get the caller id to work, but there is no phone port on it. I currently do not digital voice associated with my fios. I have the freedom essentials, which uses the regular phone line as opposed to my fiber line. They told me that the digital voice wasn't available for me. Can I do Caller ID, or is it transmitted to the 7232 via the coax cable?
