asterisk-core-sounds-fr binary package in Ubuntu Focal riscv64

 Asterisk is an Open Source PBX and telephony toolkit. It is, in a
 sense, middleware between Internet and telephony channels on the
 bottom, and Internet and telephony applications at the top.
 .
 Asterisk includes a set of standard sound files in various formats.
 The core part of that collection in Canadian French, by voice actress
 June Wallack, is contained in various encodings in packages
 asterisk-core-sounds-fr-*; this package registers these through the
 alternatives system to provide the default "fr" (French) and "fr_CA"
 (Canadian French) sounds.
