on the cable modem, that was the problem. I didn't kjnow at the time how to set the unit and there were certain settings that were locked. I was really disappointed because I wanted to buy the modem, but Cableone want way too much for it and after I lost my roommate, I went ahead and changed back to centurylink. at least I know their system works with mine, so its compatable. I bought my DSL modem so thats mine now, and I understand how to change the features on it.... Plus, the phone companies system is self resetting.... so when a call gets abandoned, the system just times out....
