asterisk-voicemail 1:16.16.1~dfsg-4build1 (s390x binary) in ubuntu jammy

 Asterisk is an Open Source PBX and telephony toolkit.
 .
 This package includes the standard files-based voicemail storage. This
 is normally the one you use and is the one that will Just Work. The only
 reason not to install it is if you want to use a different Asterisk
 voicemail storage (ODBC or IMAP).
 .
 For more information about the Asterisk PBX, have a look at the Asterisk
 package.
