Hi Alex and Richard,
After commenting out all the ip6tables there's still one warning about 'unknown option "--id"'. Evidently somewhere else it's trying to use iptables for IPv6.
Anyway, we'll check if it's actually a problem. Thank you for your suggestions!

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.
Cheers
