It doesn't even make any sense to call Background(), since there's no
caller to play prompts to, nor is there a caller who could enter digits
to select an extension to jump to.

Essentially, the only things that make sense to use in the 'h' extension
are those that don't have anything to do with the external channel that
was involved before the hangup. No audio, no DTMF, etc.
