I got a new internet connection and connected my iPhone to WiFi. After that voice call on WhatsApp or Skype doesn't work. But if I disconnect the phone from the wifi, it works.
Is there any setting that I should change to make this work?
Thanks in advance
It's a new internet contract with Telekom (MagentaZuhause). The router is Speedport smart. Everything else like mailing, browsing, streaming videos..etc are working fine. Just that I'm not able to make any voice calls.
You could try, to change the data security setting in the speedport service menu.
You‘ll find the right setting within the Internet section. There under „Internetverbindung“ (Internet connection).
Just switch there at the „Datenschutz“ radio buttons to „Aus“.
And then save the setting.
Does that change solve the issue?
I also have brought a screenshot from the user manual of speedport smart.
