Maybe you need to enable the guest to access those devices?
In the lxc guest conf file, you should probably have omething like:
lxc.cgroup.devices.allow = c 196:0 rwm # /dev/dahdi/ctl
lxc.cgroup.devices.allow = c 196:253 rwm # /dev/dahdi/timer
lxc.cgroup.devices.allow = c 196:254 rwm # /dev/dahdi/channel
lxc.cgroup.devices.allow = c 196:255 rwm # /dev/dahdi/pseudo
# For the record: you don't probably don't need the following one:
#lxc.cgroup.devices.allow = c 196:250 rwm # /dev/dahdi/transcode
