I have enabled a function in my mobile phone, that uses my home Wi-Fi network to make calls when the cellular signal does not exist. As far as I know, the cellphone provider charges me as though I make calls through its cellular network.

When I make calls using my mobile phone and the Wi-Fi network (not the cellular network), do I have A5/1, A5/2, A5/3 encryption/decryption or only Wi-Fi encryption/decryption or none of them?

I suppose that If I have both Ax/y encryption/decryption and Wi-Fi encryption/decryption I should have increased delays...but I really do not know...
