Did getting a high end router work! I have xfinity modem with 3 xFi pods all within 400 sq ft. I have great speed and I drop WiFi calls all the time! I do not get AT&T service so I depend on WiFi calling! I was told by AT&T to set up port 500 and port 4500 with protocol UDP So I was able to do so with the XFI app My wife’s phone is on port 500 and mind is port 4500. Remember when you reset network settings that changes the name of the phone back to manufacture setting! You have to rename your phone back to the name you assigned to the port! Example. My phone is iphoneglen and that’s sssigned to port 4500 If I reset network setting, then the name changes to iPhone !
