See the complaint on #4039. This doesn't fix that particular
issue (it's somewhat unrelated), but does solve around
a file parsing problem reported by @void-in
However, it's not actually being used in the module anywhere, so this
change appears cosmetic more than anything right now. However, I'm
inclined to believe Ricky's suggestions when it comes to H.323.
