Err... I guess you meant:

iptables -A INPUT -p udp -s 192.168.0.0/24 --dport 5060 -j ACCEPT
iptables -A INPUT -p udp -s 10.0.0.0/8 --dport 5060 -j ACCEPT
iptables -A INPUT -p udp -s 66.66.66.66 --dport 5060 -j ACCEPT
# only if previous three did not match:
iptables -A INPUT -p udp --dport 5060 -j DROP
