I have an Iphone 7 plus with the latest Apple update. I continue to have problems with calls being dropped when I am home and have turned on WIFI called. I have 1 bar on my verizon service and so I use WIFI calling to make calls at home. I can make a call that lasts about 2-3 minutes and then I get the "Call Failed" sign. I have reset my phone many times and I still have the problem. I noticed a few more people on this discussion have the same problem but I dont see any resolution of the problem. Please let me know if there is anything else I need to do to resolve the issue.
