WiFi (Wi-fi) calling is not working on Linksys EA8100-AH (AC2600) Router
I am wondering if anyone has come across such an issue on the same Router/gateway that i am running.
Since i switched to Starhub on this Router/gateway in mar 2019, the Wi-fi calling has not been working.
I have performed factory reset and power restart on the router/ONT several times.
I know for a fact that it is not an issue with the iphone (Iphone 7) as i have wifi calling working with the same phone in other Wifi networks in Singapore.
In addition, i have 2 x other iPhone at home that is having an issue.
Tried to do port forwarding to allow the VPN tunnel to establish but to no avail.
So it is either: Linksys router issue or Starhub Home ISP issue with establishing the VPN tunnel required for Wifi calling to work.
Mobile Phone is with Singtel but i have confirmed with Singtel rep that wifi calling is available for all Wifi based out in Singapore.
