Hi,
Fingers crossed someone can point me in the right direct on this issue, I’ve been trying to figure it out for almost a week now.
I’ve installed a digium TDM800P card on a clean install on FreePBX. The card currently has 4 FXO ports
After some browsing of this forum I can receive incoming calls and make internals calls but when I try to make externals calls I just get the ‘all circuits are busy’ message.
I’ve had a good look round the forums but none of the other posts relating to this error seem to have helped.
I suspect it’s something blindingly obvious but none the less I’m completely bamboozled.
Here’s my log file from an attempted call:
