Hello , Currently we are planing a 3CX system with 2 cloud instances on Amazon. The connection from the cloud to the local network is through VPN connection. What is the best solution in order to work ? We don't want to provision the extension through the FQDN and go public but with the private vpn network. A local split dns will work in that situation ? and with the help of a script in the passive to change the local ip of the active to the passive and make the registration of the extensions ?
