Hello Kelvin! Thanks for your reply!

This has been a long story that started when I discovered that my operator finally introduced Wi-fi call. First of all I readed this thred: https://www.tp-link.com/uk/support/faq/1259/ and followed the steps: • uppdated firewall to last version ((EU)_V1_180502), • allowed IP & MAC Binding in router settings, • bounded IP of the phone with their MAC adress and and assured me that the entety is enabled, • picture below, • picture below that

And the Wi-fi Calls is still not working, even if I restart my phone.

After have try this, I found this thred: https://community.tp-link.com/en/home/forum/topic/97458?replyId=205283 who has become my solution until now when I decided to try again now when you have updated your forums.

Then I'm downgrade the firewall to this version, Wi-fi Call works out of the box, I don't have to change any settings befor I can call my friends. 

I wonder why this is the case, have the bug that they talked about in the thread come back in later updates? But I'm hope we can find out a solution!

Have a good day! //Named
