High availability installation The installation wizar Software Code 39 Full ASCII d is able to install and configure a highly available system that consists of two physically separate servers. A High Availability (HA) system consists of a master server and a distributed server. Failover is taken care of by utilizing DNS SRV records that include information about master and distributed servers.

The HA system allows redundancy of the call control system and load balancing of traffic. Media services such as voicemail, auto attendant, and other services such as ACD and sipXconfig are not redundant and will only run on one of the master server. For a high availability installation, the master server must be installed and configured first.

The installation procedure is similar to the steps taken in the previous section to install and configure a non-redundant system. Configuring the distributed servers of the cluster begins at the bootstrap portion of the setup. It is required that you run DNS and NTP services both on the master and distributed system unless you have a different setup that provides these services in a reliable way to both systems.
