Wi-Fi calling not working on Deco M5s
I have Deco M5s (4 of them) nicely setup across my flat. For some reason, Wi-Fi calling does not work.
I remember it worked earlier but can't exactly remember when was it.
My ISP is ACT and I have a 300MBPS plan
We have an Iphone and android phones. Wifi calling does not work on both of them
Our cellular service provider is Airtel and if Wifi calling works, we can clearly find the difference in the calls as well as "Airtel WiFi" is displayed on the screen that shows cellular name.
I also have a NetGear Nighthawk router and Wifi calling works perfectly when we use it.
Wondering if anyone came across this.
