[danry25]

The readme indicates that the index numbers of a device are usable, but setting pjsua-device = 1 or similar results in the crash shown below.

I fixed this in the git version, as mentioned to you on multiple occasions in the long chat we had few days ago, don't you remember?
Now you're trying to use old version and get same exact error.
I'm confused about the thought process here - yes, sure, old version had a bug, use fixed one.

[mk-fg]

Double-checked for whether I maybe forgot to push it, specific fix is this one:
080ca3f#diff-c6353a73b3f5034b1f9661701ec297bfR625

Bundled it with other fix for error imports, so maybe that makes it less obvious, though still no excuse for complaining about the several-years-old version when I specifically told you to use the fixed one from git :)

Oh shoot, my apologizes. It looks like I have an old copy of paging.py, let me update and retest.
