Hi,
We have a Digium B410P BRI 4 port ISDN Card installed and is configured via DAHDI.
In bound calls are working fine, Audio works both ways. I only have a single line plugged in at the moment and the Span 1 Alarm is showing as being OK.
When we try to dial out we get the “all circuits are busy” message. I have checked everything i can think of and it all seems to be OK, i am presuming the issue could be to do with a dial plan. However i have been reading that various threads that as I’m in the UK our Telco ( British Telecom ) switch off the D Channel and we may need to configure the card settings to not bring it up.
I have read and tried various suggestions made in these forums and others and not getting anywhere so have had to resort to asking for help.
FreePBX version - 12.0.18
Asterisk version - 11.14.1
DAHDI Version: 2.10.0.1 Echo Canceller: HWEC
below is a copy of my Chan_DAHDI.conf file… not sure if anything else is needed.
Many thanks in advance
