Azure VM opening ports to talk to asterisk ami

Question

Attempting to open ports to allow app to talk to asterisk AMI interface.

opened the port outgoing on the network interface and made sure the windows firewall isnt blocking it

tried to use telnet to open a connection to the port on the asterisk machine but it fails

for testing even tried to open all outgoing ports but it still failed.

what could i be missing?

thanks

Hi @Michaek Salzlechnner

Try To verify that the port is actively listening, you can execute the command telnet localhost <port>. Make sure to replace <port> with the actual port number that the Asterisk AMI interface is listening on, typically 5038. This command will help you confirm that the connection to the specified port is successfully established without going through the firewall

If the service is running locally, make sure there isn't a conflict in the Network Security Group rules, usually the NSG is bound only on the VNET, but there are cases that you bind on both the VNET and the NIC, if you have two nsgs, make sure that the inbound rule is currently configured on both

You can go to Network Watcher -> Effective security rules - to verify which NSG are associated with your VM

just like:

You can also run "NSG Diagnostics" to verify if there are any deny rule, just like:
