Since I had to use my own domain name to be able to access the sip server from the internet, I needed a rule to forward the media stream from behind the nat. So I had to add
> $IPTABLES -t nat -A PREROUTING -d external-ip -p udp -m udp --dport 20000:40000 -s 192.168.15.0/24 -j DNAT --to-destination internal-ip-sip-server:20000-40000
