Re: Calls cut off at exactly 30 minutes Yes! My calls drop all the time, almost every call, for the last month. Bought new phones, rebooted the modem many times. Have spoken with tech support, they sent out tech to replace modem and he told me they are having problems with modems, would do no good to put in a new one, as it is happening with those as well. Problem with software and they have no idea when it will be fixed. I need a reliable landline. Can anyone at Cox address this issue? Dropped Calls Calls on my landline have been dropping calls for the last month. I have tried tech support with no help. Tried new phones, rebooting modem and nothing helps. A tech was sent out to replace modem and when I explained problem he said many customers are having this problem, it is a glitch in the modems software, and even replacing with new will not help as the glitch is in there as well, and no idea when it will be fixed. I am so upset that I do not have a reliable land line. Can the moderator shed on this problem?
