trixbox Pro offers VoIP-users a PSTN back-up in case of an Internet service interruption. The PSTN fallback automatically kicks in when it detects poor, or no, internet connection, switching your system over into PSTN mode.
All the configuration setting are stored in the cloud, independant of your trixbox deployment. This means revisions of your configuration are kept and individual server settings can be stored effortlessly in the event of server damage.
The LBS is a warm mirror server situated in proximity to the live server. In the event of primary server failure LBS can be brought up online very quickly.
