Core Issue

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:

  1. A caller calls a Cisco Unity server on which an audio text application is configured.
  2. 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.
  3. The Cisco Unity server that handles the call puts the caller on hold, and calls  the subscriber home Cisco Unity server.
  4. 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.
  5. The destination server responds with a sequence of DTMF tones.
  6. 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. 


Refer to the Cross-Server Transfer from the Automated Attendant and Directory Handlers section of Cross-Server Logon, Transfers, and Live Reply for information on enabling cross-server transfer on Cisco Unity servers configured with Cisco Unity networking. 

Verify these settings on the Cisco Unity server:

  • Under Unity tools Depot, select Administration Tools > Advanced Setting  Tools and make sure that Auto Attendant Search Scope is set to 1.
  • On the System Administrator web page, select Network > Primary location > Dialing domain to check that both the servers are under the same dialing  domain.

Note: Reboot the Cisco Unity server after you make changes in the  Advanced Setting tool because this includes changes in the registry.
