5060 Does not seems to be open

For some reason, the port 5060 seems to be closed and I do not know exactly why.
When I run an nmap command I get this back

Starting Nmap 6.40 ( http://nmap.org ) at 2019-11-07 18:30 UTC

You can see there is no port 5060

When I look at the specefic port it is saying that it is closed

[[email protected] ~]# nmap -v -sV localhost -p 5060

With a netstatus I get the next

[[email protected] ~]# netstat -na |grep 5060
udp        0      0  *

Where is it going wrong?

You are looking for tcp ports by default

lsof -i :5060

works ubiquitously as to what services are running, what gets through the firewall is another thing

This is what I get when I run the command.
How can I make sure this port is open?

[[email protected] ~]# lsof -i :5060
asterisk 2098 asterisk   24u  IPv4  24919      0t0  UDP *:sip
[[email protected] ~]#

From the outside of your firewall you can use netcat

nc -v -u -z -w 3 your.pbx.external.ip  5060-5061

leave out the -u to check for TCP

I think it was an update or something I have put back a snapshot and it is working again
