Bug#848584: asterisk: missing hook for automatic load of DAHDI channels

[Tzafrir Cohen]

Package: asterisk
Version: 1:13.12.2~dfsg-2
Severity: wishlist

Dear Maintainer,

The package dahdi (of source package dahdi-tools) includes the directory
/usr/share/dahdi/span_config.d/ for scripts that get called (from udev,
through a hook script) when a new DAHDI span appears. The allow applying
custom operations on the span.

As of version 1:2.10.0.1-1 of dahdi (now in Jessie) the Debian package
has removed the hook that registers spans with Asterisk automatically[1]
because this is the job of the Asterisk package (DAHDI should not tie
itself to Asterisk).

Thus this script should be added to Asterisk.

If one wants to avoid a file conflict with dahdi <= 1:2.10.2-1
(pre-jessie versions), it should be safe to use the name '40-asterisk':

* Calling the script twice (in case that older version installed) has a
  small performance issue, but nothing more.
* This number (40) is already used in some unofficial packages used by
  the company I work for.

I recommend to add it to the main package (asterisk) and not to
asterisk-dahdi for the sake of simplicity: it does not add any real
dependency on dahdi.
