All Circuits are busy


I installed FreePBX and configured an extension. I can make an echo test call to the server. I added my VoIP.MS account as a SIP trunk. It shows up in FreePBX as registered as well as in the VoIP.MS portal.

When i make an outbound call I get the all circuits are busy message from the server. Here’s something in the logs…

I replaced the # being dialed with XXXXXXXXXX and my account # with 123456… VoIP.MS doesn’t see the call come in at all so looks like FreePBX doesn’t ever get there.

The fact that the SIP trunk shows up registered lets me think the credentials aren’t the issue…

For troubleshooting i tried disabling both the FreePBX firewall and my UDM Pro Firewall to no avail.

I’ve seen some info on the NAT settings as well. I tried both Public/Static/Dynamic. no luck.

asterisk -rx “sip show peers”
Name/username Host Dyn Forcerport Comedia ACL Port Status Description

voipms-in/123456 Yes Yes 5060 OK (23 ms)
voipms-outbound/123456 Yes Yes 5060 OK (23 ms)

asterisk -rx “sip show registry” Y 280155 105 Registered Wed, 26 Aug 2020 07:43:04

Any ideas?


Ugh… i’ve got it now.

problem was the IT guy writting the config. Me :slight_smile:
