QSIG allows users on a remote node to “cover” to an AUDIX on another node. The original calling and called party information is provided to AUDIX so that each is identified properly during message recording/retrieval.

To use centralized AUDIX, you must use QSIG Diversion. On a remote switch, the call covers using Diversion to the hunt group assigned to AUDIX on the host switch. Then the host switch sends all the appropriate information to AUDIX so that AUDIX correctly answers the call.
