Hi

I'm using 3x Deco M4's in my home a along with one deco m3w to help the signal along in a hard to reach area of my home. All the latest firmware etc etc.

Issue is that whenever any of us in the house make a call using WIFI calling it cuts out after five seconds. Total nightmare. I have to turn the wifi off on my phone to make calls. im using  ID mobile but having read online it can happen with any network.

Happens everywhere in the house. I've tried using port forwarding. No difference. Moving devices. Nothing works...help! Thanks
