Hi All, I have a system here which I have previously been running Trixbox on, and now decided to look at Elastix but having an issue installing my Sangoma Hardware. This machine has an A500, A101D and an A200 installed in it. I run setup-sangoma and it asks me questions about the hardware, when I tell it to restart asterisk then I get the following: Unloading Dahdi modules... FATAL: Module dahdi is in use. Error executing command: modprobe -r dahdi Rebooting the machine doesn't help and the cards aren't working. I have tried just a "yum update" but to no avail - still the same error occurs. Anyone any ideas of where I need to look / what I can do? This hardware was known good on Trixbox so it must just be the install that I'm doing wrong / has an issue!
