Hello,
I am not sure what do you mean with:
"""
I have noticed that if Kamailio is IPv4-only and it "sees"
IPv6-addresses(Contact, Via headers??) it will try to resolve the
IPv6-address as a DNS name!
"""
If it just that on the specific deployment Kamailio has to bind on IPv4 and
run as an IPv4 application, or actually you mean that Kamailio does not
support IPv6?!?
For the later, Kamailio supports IPv6 for quite long time and should work
fine on IPv6 only or mixed networks.
Cheers,
Daniel

Hi folks,
I'm wondering what you do to pass Apple app store tests (IPv6-only
NAT64/DNS64 scenario) with the iOS app likely to put IPv6 addresses in
the SDP, when Kamailio and your B2BUA(Asterisk, FreeSWITCH,...) are
IPv4-only endpoints.
By "pass" I mean media flowing + SIP working - not sure the app store
gatekeepers would actually test media, but it would be nice to have a
robust solution.
Strictly speaking, this is not a Kamailio's problem but a media
SDP/<your-rtp-proxy-of-choice> problem. But since everything is so
closely intertwined I'm wondering where you choose to the location the
"solution".
I have noticed that if Kamailio is IPv4-only and it "sees"
IPv6-addresses(Contact, Via headers??) it will try to resolve the
IPv6-address as a DNS name!
The Wikipedia article on NAT64 mentions 464XLAT(RFC 6877) and Port
Control Protocol (RFC 7225), but those seem to be deep rabbit-holes...
