From Release 9.1, IP Office Release supports two methods for ensuring continued DECT availability. Both methods can be combined to ensure maximum availability. In both case, it is recommended that normal installation of the system is completed and tested before then adding mirroring and or switch resilience.
Master Base Station Mirroring: It is now possible to configure two base stations to act as 'mirrored' master base stations. One becomes the active master base station whilst the other becomes a standby master base station. If for any reason the active master base station becomes unavailable, the IP Office switches to using the standby master base station to continue DECT operation. Mirroring is not supported between compact and non-compact base stations. However, it is supported between a DECT gateway and non-compact base station.
IP Office Switch Resilience: The IP Office controlling the DECT system can be configured to allow that control to be automatically passed to another IP Office system when it is not available. The SCN line between the two systems can be configured to allow DECT backup for resiliency scenarios in the same was as existing resilience for H.323 IP telephones. If for any reason the primary IP Office system becomes unavailable, DECT control and users are switched to the backup IP Office system.
