[Freeswitch-users] vm-keep-local-after-email vs vm-delete-file?

Hi, is vm-delete-file deprecated in favor of vm-keep-local-after-email? I can only find the latter in the wiki now (http://wiki.freeswitch.org/wiki/Mod_voicemail#vm-keep-local-after-email). Are they supposed to do the same? The recorded mp3 files aren't removed for me, anybody else experience that? Regards
