If you are trying to open a range ports for firewall follow one of solutions.

In case you are using IPTABLES:

sudo iptables -A INPUT -p udp -m udp --dport 5060 -j ACCEPT
sudo iptables -A INPUT -p udp -m udp --dport 10000:20000 -j ACCEPT

It is very probably that you are using IPTABLES so I recommend you to go with it.

If you somehow use ufw following will help:

sudo ufw allow 5060/udp
sudo ufw allow 10000:20000/udp

Good luck :)
