Could I have some how accidentally blocked all incoming calls? Since like I said before that when someone tries to call me. They get your call not be completed at this time message. Even though I can make outbound calls.
Have you upgraded your telephone modem since Cox transitioned to VoIP?
So I got to go and get a new modem again? I just got a new one back in Jan of 2019. So no one can call me right now till I do. But I can call others.
The phone modem could be a different one than the Internet Modem. In my house, I have a separate modem inside the box that all the COX wires come to before they are sent out thru the house and to the phone jacks. There also are coaxial cables sent out to some of the rooms to which I connect my TV/DVR or one to my internet/wireless modem. I'm not sure how your modem connects to your phone, unless it is wireless or you are using strictly cell phone connections. If you are having problem using a landline, and you do not see a phone jack connection from the modem u had in 2019, maybe there is another phone only modem stuck in the closet that is bad or needs re-boot by pulling power cord. Just wondering.....
I think I figured it out. For some stramge reason they now have to add the area code to my number even if they are in the same area code as me.
@Horserider1st Are you saying that until recently, you've been able to make phone calls to numbers within your own area code with just a 7-digit number?
