This package is based on the package 'asterisk-addons' from project 'network:telephony'.

Asterisk is a complete PBX in software. It runs on Linux and provides
all of the features you would expect from a PBX and more. Asterisk
does voice over IP in three protocols, and can inter operate with
almost all standards-based telephony equipment using relatively
inexpensive hardware.
This package contains additional addons for asterisk.
