I recently converted from FIOS to cable phone service (VoIP) (my FIOS contract was up and the cable compan offered me a better deal over the next two years -- no complaints about FIOS itself). Since I converted, I've been having all kinds of problems with the phone service, and all of the problems exist only when I use the house wiring -- when I connect a phone right to the cable modem, it works perfectly. I disconnected the ONT's battery backup unit and unplugged it, but that caused me to lose the dial tone after a few seconds -- I got nothing, and then a fast busy (again, this happened only when I was connected to the house wiring -- it didn't happen when I used a phone that was connected directly to the cable modem). Putting the battery back into the ONT's battery backup and plugging it back in corrected that issue. Additionally, I don't get a triple beep when I pick up the phone if there's a voice mail, nor does the phone's display screen indicate that there is a message waiting. In short, it appears that the house wiring is still connected to Verizon's system. The cable company says the house wiring isn't connected to the old (analog) Verizon box outside the house, but it says it can't touch the ONT. Do I have to have Verizon come over to disconnect the house wiring from the ONT, or can I do it myself? If Verizon comes to do it, will I get charged? Thanks. David Ross {edited for privacy}
