Reading further into this error message, it sounds
like you are using an
init script for RTPengine which attempts to install the -j RTPENGINE
rule for both the IPv4 and IPv6 netfilter tables, which are separate,
using iptables and ip6tables respectively. I believe that is what the
stock Sipwise init scripts / systemd units do.
If IPv6 is disabled on your host, that's not going to work. Try
commenting out the ip6tables line (but not the iptables line) in the
rtpengine init script / unit and see if it makes a difference.
IPv6 not being
available would also be my guess for an explanation, and
would also explain the original error (control UDP socket not being able
to be opened) as by default the control socket would be opened for both
IPv4 and IPv6 also.
