we have 4 sites each with its own 3300 ICP. The sites are part of the same cluster but i wanted to know if it was possible to have them act as 1 device for example:- we use hotline nummbers and at present we can assign a hotline number on one controller but cannot assign it to a phone registered on another controller on the cluster.
in the system admin, datasharing is turned off and PNI has no value.
i know on cisco systems this can be done, where calls are routed internally normally but if the link goes down the internal calls are routed via the PSTN back to the main controller. external calls break out locally to.
many thanks
