Do you have something in /var/spool/cron/asterisk ?

Maybe @thorsten can help you:

Asterisk module and its ghosts

Hi Forum, Some month ago I installed the nethserver-asterisk module. I tried to remove from web frontend, but this was rather difficult. The nethserver module was removed while individual asterisk modules remained on my system. The solution provided by @mrmarkuz helped, but there is still one ghost left. Something derived from asterisk sends more than 600 email per day… How do I get rid of those nasty shadows? [grafik] TIA Thorsten NethServer Version: 7.9 Module: Asterisk
