What is the best way to find out address family (IPV4 or IPV6) of media in SDP?
My goal is to reject INVITEs which have different address families in headers
and SDP, i.e. IPv4 INVITE with IPv6 media address in SDP and vice versa.

Hi, maybe something like this works:
if(sdp_get_line_startswith("$avp(cline)", "c=IN IP6")) {
xlog("c-line: $avp(cline)\n");
}
I did not test, just copy-pasted from documentation:
http://kamailio.org/docs/modules/devel/modules/sdpops.html#sdpops.f.sdp_get…
Be aware that SDP can have multiple c-lines, so you propably want
to scan SDP more extensively.
Best regards
