A cross-server transfer is a special kind of supervised transfer that passes control of a call from the automated attendant or a directory handler to the home Cisco Unity server of the called subscriber. This is the process:
A caller calls a Cisco Unity server on which an audio text application is configured.
The caller performs one of these actions:
The caller enters the extension of a subscriber on another Cisco Unity server in the dialing domain in a call handler (such as the opening greeting). or
The caller spells the name of a subscriber on another Cisco Unity server in the dialing domain in a directory handler.
The Cisco Unity server that handles the call puts the caller on hold, and calls the subscriber home Cisco Unity server.
When the destination Cisco Unity server answers, the originating Cisco Unity server sends a sequence of DTMF tones that identify the call as a cross-server transfer.
The destination server responds with a sequence of DTMF tones.
The originating server hands off the call to the destination Cisco Unity server for processing. At this point, the behavior is as though the caller had directly called the automated attendant or directory handler on the destination Cisco Unity server.
