I can load the drivers ok:
but then when I run /sbin/ztcfg -vv, I get:
root@UbuntuBox1:/etc# /sbin/ztcfg -vv
Channel 01: FXS Kewlstart (Default) (Slaves: 01)
1 channels configured.
Changing signalling on channel 1 from Unused to FXS Kewlstart
ZT_CHANCONFIG failed on channel 1: Inappropriate ioctl for device (25)
My question is, what does "Inappropriate ioctl for device (25)" mean, and how can I fix it?
