Is it possible to have FREEPBX system acquire HA ready for installation? If we decide your HA solution, we like to start the setup as soon as tomorrow afternoon 3 pm Singapore time. Server specification is on this link below. [login to view URL] We already have the FREEPBX installed now waiting for a decision to get the best HA solution for this servers. The HA must support the following features. 1) If primary server power goes down, secondary server must take over automatically 2) If primary asterisk service hangs, secondary server takes over 3) If the any of the services running supports the PBX service such as Mysql, Asterisk, FREEPBX goes down on primary srv; secondary server takes over 4) If the primary SRV network goes down, secondary takes over. 5) If Asterisk is behaving strange or service is having a bad sector in HDD, the secondary takes over. Please advise if this can be done.
