dpkg has not only Depends but also Recommends (packages that SHOULD BE
installed for the package to work properly, but can not a strict
dependency) and Suggests (nice-to-have provisions).

We currently have asterisk-dahdi as a Suggests.

Asterisk uses libtonezone from dahdi-tools (right? Just chan_dahdi?).
Asterisk-dahdi are all the modules that will not work without DAHDI
support: chan_dahdi, app_meetme, res_timing_dahdi, codec_dahdi, and a
few other minor modules.

The kernel modules are from a different package that is independent of
Asterisk. It is also a package that will not get into Fedora any time
soon. It has two licensing issues:

1. binary-only objects optionally used to build some of the modules.
2. firmware files.

(2) can be fixed in retrospect at distribution time. But (1) has to be
tended to at build time. The Debian packages thus fail to include (1)[1]
and sort-of-work-around (2) with a package in non-free[2].

[2] Debian's firmware policy is stricter than Fedora's, and some of the
firmwares will be legal for Fedora. The ones not currently not even
included in the Debian package will not.
