I am having the same issue with dropping calls. Me and my wife both have Iphone 6s. I have had AT&tT for more than 15 years and never had dropped calls. She works in a office with poor cell service, but under AT&T she never dropped calls.I have been trying for the last week or so with different settings,Turning off and on WiFi calling,Turning off and on Voice over LTe to islolate the problem with no sucess. I was searching online and came across this thread and and somewhat relieved that i am not the only one experiencing this issue.Its rather frustrating that we both have call failures. We both have to call eather other 2 to 4 times to establish a connection. I am not sure if its just WIFI Calling but i am still trying to figure it out. I am saving nearly $90 a month on our service but if i cant make a call what am i really saving? I will continue to try to diag the problem and will not waste my time calling Xfinity for there help. If i find anything new or a solution i will shae it with the board.
