•Automatic Provisioning/Centralized CTI Mode
For a portal server supporting a Linux-based IP Office network, the server can be informed by the primary IP Office system about other IP Office systems in the network and about the voicemail server. It then automatically adds or removes the appropriate providers for those other systems. This is done using the Central CTI Link setting, which is on by default for new installations. When enabled, manual configuration of providers for additional IP Office systems is not necessary. In centralized CTI mode:

•If not using resilience, the server only requires a DSML provider to the primary IP Office system.

•If using resilience, the server only requires a DSML provider to the primary and secondary IP Office systems.

•The server only requires a CSTA provider to the primary IP Office system unless using portal resilience in which case it also needs a CSTA provider to the secondary IP Office system.
