Outbound calls work fine, but inbound calls are not being received

[moskovic99 (Mustafa)]

Hello,

We are experiencing issues with inbound calls on our FreePBX system. The details are as follows:

Network Configuration:

• The router is directly connected to the server hosting the virtual machine.
• The router’s firewall is disabled, and all traffic is routed to FreePBX via DMZ.
• Ports 5060 and 5061 are also forwarded to FreePBX.

Observations:

• When checking the external IP’s 5060 port with netcat, it appears to be open.

• Outbound calls work fine, but inbound calls are not being received.

Additional Information:

• Our trunk and inbound route settings can be seen in the attached images.
• Trunkt Settings

Asterisk Sip Settings

• The FreePBX firewall is disabled.

• Zoiper application works on the local network but not when connected from an external network.

We would appreciate any assistance you can provide on this issue.

Thank you.

Outbound calls work fine, but inbound calls are not being received.

What happens when inbound calls come in?

Also I see port checker is reporting the ports are closed

When calling the phone from outside, it says “out of service.”

Correction: Asterisk is not listening on ports 5060 and 5061. The port is open, but when I check, it shows as closed.
