iPhone Wifi Calling
Does anyone have Wifi Calling working on their iPhone?
It was working for me, but recently stopped and I can't figure out why (I suspect it may be due to the net neutrality repeal).
AT&T is telling me that it requires port 143 to be opened, but Cox is indicating they block that port for all residential users, but they can't tell me when the change was made.
One of the Cox support agents gave me a song and dance about how I need to open the port on my CABLE MODEM, but that turned out to be BS.
Someone, please help!!!
This wasn't the solution, but it pointed me in the right direction. Thanks!
I can confirm that iPhone WIFI calling absolutely works on Cox's internet service.
My issue was my router's (TP-Link Archer C2300) configuration.
WIFI Calling requires IPSec Passthrough. On my particular router, this was disabled.
Blocked ports was not an issue.
