Hi,
I have FreePBX on AWS EC2 server
But when I checked for the UDP port 5060 I found that it’s closed
I’ve added it to the security group but it’s still closed
The problem is that I was trying to link the FreePBX extinction to lingphone app and it keeps telling me that the account does not exist so I am not sure if it’s a port problem or what?!
confirm the service port to insure its not something other than 5060 … settings > asterisk sip settings > then the channel specific tab and look at the port to listen on for UDP 5061 is typically TLS and thus TCP not UDP
finally make sure you are not banned in some manner or blocked by local firewall policy in connectivity > firewall… look at networks and intrusion detection
if you still cannot reach the service port its something in between, like AWS firewall policy
