Today I made a phone call to another office. Both offices (mine and the remote office) are running the latest stable FreePBX with all updates installed.
When I made the call there was a pause, and then a voice came on the line saying "Congratulations! You've won blah blah blah! Press 1 for this..."
At that point I hung up and dialed the number again - this time it went straight through to my destination without issue.
My office is behind a firewall with no open ports (we use VPN for external extensions) and the destination is behind a very basic router/firewall also with no open ports. We have strong passwords for every extension and the freepbx admin itself.
So my question is: is this a problem on at the destination (where I was calling to) or the source (where I was calling from) and how can I eradicate the issue? I haven't been able to replicate since...so I'm having trouble seeing anything in the logs.
Thank you for any advice you can give!
