I upgraded an existing Bookworm server to Asterisk 22.10.1+asl3-3.10.5-1.deb12. After the upgrade, I started seeing "Error loading module 'chan\_voter.so': /usr/lib/x86\_64-linux-gnu/asterisk/modules/chan\_voter.so: undefined symbol: ast\_radio\_tvnow" on startup. I initially wondered if the issue was with my Bookworm installation. I performed a fresh install on Trixie, and when I moved my configurations, I encountered the same error. Web searches yielded no relevant results. When I reverted to stock configurations, there was no error. This prompted the question: why were my configurations suddenly broken? I eventually discovered that I needed to load res\_usbradio.so. I did find the commit, I did not see where it was needed for voter.

I have two requests. First, I suggest a slightly more descriptive error message. My server does not have any USB devices connected, so my practice is to disable any unused or unneeded modules.

Summary:

If you encounter this error in your logs:

Error loading module 'chan\_voter.so': /usr/lib/x86\_64-linux-gnu/asterisk/modules/chan\_voter.so: undefined symbol: ast\_radio\_tvnow

enable res\_usbradio in modules.conf.
