Messaging interoperates with the Transfer to Messaging feature of Communication Manager. The feature is also called Transfer to AUDIX.
With the Transfer to Messaging feature, the operator or attendant can transfer the caller directly to the mailbox associated with the originally dialed number. The transferring party does not need to re-enter the originally called number, and the telephone of the originally called number does not ring again. For other PBXs, Messaging uses a caller application to transfer a caller directly to a mailbox.
