I was just looking at the pbxportal script to see what ownerships need to be changed to run as root and I came across an error (of omission). The script sets ownerships for /dev/zap, /dev/capi20, /dev/misdn, and /dev/dsp, but it completely forgets /dev/dahdi. Not changing the ownership of /dev/dahdi means PSTN lines aren't going to work.
