Yup, looks good to my eye.
If you get a 'green' "Firewall has Restarted." in the web interface after {
Restart Firewall } that implies there are no iptables errors.
If you want to test deeper, issue from the CLI, you should see something like
...
# iptables-save | grep '125.213.160'
--
-A EXT_INPUT_CHAIN -s 125.213.160.0/22 -p udp -m udp --dport 5060 -j ACCEPT
-A EXT_INPUT_CHAIN -s 125.213.160.0/22 -p udp -m udp --dport 16384:17384 -j
ACCEPT
--
