All circuits are busy now - Unable to make outgoing calls

After configuring sip trunk and adding an extension, I am able to receive incoming calls, but I can make outgoing calls, i keep receiving the error “All circuits are busy now, call again later”.

Peer details:


I have configured an outbound route. FreePBX on a virtual machine.
Asterisk Version: 13.22.0
What is causing this type of error?

Can you post a call trace?

Where are you sending the call? From your post, you are saying the ITSP Server address is “dynamic”. That isn’t going to cut it. You need to server name or IP address, at the very least.
