All circuits are busy please try call again later

Hi,

We have been using the freepbx from 2 months but nowadays i get the message while dialing a number “All circuits are busy please try call again later”.

Please help.

Thanks

check your dial plan… in other words if your dial plan (for dialing out) looks like:

1NXXNXXXXXX

and you try to dial

312-300-0000
You would get this message.

Another thing to look for - registrations of your trunk(s).
