backport asterisk to bookworm

[C. Maj]

Howdy,

Very fine project and thank you to Jonas for keeping it up-to-date.

I've followed several discussions on lack of Asterisk in Bookworm, 
including the [Debian Bug report 
#1031046](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1031046) and 
a related [Asterisk forums 
topic](https://community.asterisk.org/t/status-and-perspectives-of-asterisk-package-on-debian-bookworm/97087), 
finally signing up for this mailing list and reading those threads over 
the past several months, as hopefully this is the place where it all 
comes together to get the backport back in action.

After installing all of the necessary dependencies and following the 
first few steps of the [VoiP team 
HOWTO](https://wiki.debian.org/Teams/VoIP), I was able to build the 
latest asterisk 20.6.0 LTS package on bookworm with the addition of one 
new file placed as debian/backports/bookworm... I think such an easy fix 
is testimony to the quality of the package in trixie!

The step-by-step from a Debian 12.2 minimal/ssh install:

Following up on chat to make this a thing...
