I was looking into the same thing regarding VoWifi, as that was my only issue when trying to go full "IPv6 preferred". Turns out Tayga does support the RFC (7915) that handles these 0 length checksum fields.

A value of `udp-cksum-mode fwd` or `udp-cksum-mode calc` in your `tayga.conf` should fix the issue, assuming all else is in place. As soon as I did this, it started working locally (on my iPhone at least).
