Ja genau, ich habe gerade noch ein wenig zu dem Thema gelesen und sowohl O2 wie auch T-Online nutzen auch die beiden Ports. Eben so sind es die Standard Ports für eine VPN Verbindung zB. (Fritz VPN). Hier noch etwas von Netgear zu dem Thema.
We have poor cell coverage at home and can only make cell calls using wifi calling.
To support wi-fi calling for AT&T (and I think most other cell carriers) the following ports need to be open:
Port = 500, UDP, Service or Protocol Name = WiFi Calling, RFC = 5996, Service Name = IKEv2
Port = 4500, UDP, Service or Protocol Name = WiFi Calling, RFC = 5996, Service Name = IKEv2
Port = 143, TCP, Service or Protocol Name = IMAP, RFC = 3501, Service Name = Imap
