PRI maintenance - Stopping a single span

I’m not sure if this has been covered elsewhere, my searching didn’t return anything but I could have missed it.

Using any recent version of Asterisk with Sangoma PRI cards. How do you stop/restart a single PRI when the “wanrouter stop wanpipe1” returns busy with DAHDI. I don’t want to bring Asterisk down.

Is there any way to do this?


How about using

at Linux shell to restart the dahdi driver.

Kernel modules should not unload if they are in use. If they do, unload they will braak the running Asterisk, and possibly make the whole system unstable.
