Here my phone is from the cable co and if my phone stops the cable co replaces the MTA if need be.
You didn't tell which VOIP service you used and you can't replace a MTA like you are asking.
If one has internet and phone service through Cable, I know you can buy your own modems and routers, but is there a particular kind of modem you'd need to get to support VOIP for the phone?
A friend of mine has phone through Cable and her internet and phone suddenly stopped working, although her TV service is fine. We are thinking that maybe the cable company's modem is bad, so she wants to buy her own modem, but we're not sure if it needs to be a particular type of modem. I've looked around for her, but haven't found anything in modem specs stating they support VOIP. Does it matter? Or can you buy any cable modem?
We already looked at the cable providers website to see their supported modems, but they are all the same brand as the one she has that doesn't work. She already has a wireless router, which she will plug into the modem she buys, so we're only looking for answers regaring a modem.
Any help would be appreicated!
