Hi,
My primary local DNS is 192.168.1.4 (pi-hole) and secondary router's interface (192.168.1.1).
I was investigating some Whatsapp call issues on my wife's iPhone and noticed something weird in tcpdump (was taken on AP). Please see below:

It looks like the iPhone quite frequently sends STUN Binding Request towards pi-hone. Is it expected?
Just want to know if it's normal even if nothing to do with the actual issue.
Thanks, Myky
