UDP 5060 port is closed

Question

Hi, 
I am trying to open port 5060 in EC2 security group 
But even if I add it 
it's still closed

Custom UDP	UDP	5060	0.0.0.0/0	–
	–	IPv4	Custom UDP	UDP	5160 - 5161	0.0.0.0/0	–
	–	IPv4	Custom UDP	UDP	1194	0.0.0.0/0	–
	–	IPv4	Custom UDP	UDP	10000 - 20000	0.0.0.0/0	–
	–	IPv4	Custom UDP	UDP	5060 - 5061

Answer

How can you tell it is closed? What tool(s) are you using to test? On the instance (assuming it is Linux - you don't mention your OS) you can [use a few tools](https://www.cyberciti.biz/faq/unix-linux-check-if-port-is-in-use-command/) to see if the operating system is listening on that port because remotely initiated tests may not be reliable for UDP (no pun intended).
