How to install the base Monitoring Connector on a isolated Centreon 23.04 open source version ?

Hello, i’ve installed a Centreon 23.04 Open Source on a isolated network that cannot access internet, even through a proxy. I can only transfer files (like a tarball) to this environment.How can i install the free Monitoring Connectors on this Centreon ? Like Base Pack, Linux SNMP, Windows SNMP etc …I know that i can easily install the plugins (from the centreon-plugins repo) but i want to install the full pack (with the commands, services templates and hosts templates already configured in the GUI)Thank you in advance,Maxime

Hot to check asterisk 20

Hi,we have numerous Asterisk servers with version 16 with “sip” configured.Centreon plugin “Asterisk VoIP Server” with mode “sip-peers-usage” and “channel-usage” is perfect for us.(This https://docs.centreon.com/pp/integrations/plugin-packs/procedures/applications-voip-asterisk-ami/)Using Asterisk Manager Interface (AMI) we can monitor all problems we can have, both with virtual servers and physical ones with dadhi.The problem is that we are migrating to a more recent verison of Asterisk (20.4.0) and we are moving to the pjsip protocol but it seems that centreon doesn’t have a proper mode for this.In other words, If we use the same “mode” mentioned before, we get this error:“UNKNOWN: Communication issue [Message: Command output follows -- No such command 'sip show peers' (type 'core show help sip show' for other possible commands)]”And this make sense because Asterisk, for the pjsip protocol, uses different command like:*CLI> pjsip show endpoints*CLI> pjsip xxxx xxxxFor what i ca
