i’m asking if it’s possible to know the time of the last quintum registration in the gatekeeper, i need this parameter to know if there is a line cut or not
You can disable telnet access by setting the managementaccess command to 0 and submit. Once you do this, you will be able to continue your current telnet session, but once you log out, telnet and ftp will be disabled and only console connection or config manager connection will be allowed.
I am not sure I understand the billing question, but the quintum does provide cdr records that you can get.
