update May 24 did not go too well abandoned upgrade to ubu 24 after disk failure went back to ubu 20 with Asterisk 18 followed the instructions contained in this document (for the most part) with these more up to date ones https://reintech.io/blog/setting-up-asterisk-voip-server-ubuntu-22 seemed to hit problems related to user groups and settings The edits below -cause problems – so i have revised them in the instructions sudo gedit /etc/default/asterisk
