Enhanced Call Transfer

About this task

With Enhanced Call Transfer, the messaging system uses a digital control link message to initiate the transfer, and the Communication Manager server verifies that the requested destination is a valid station in the dial plan. With Enhanced Call Transfer, when messaging callers press * 8 followed by digits (or * 2 for name addressing) and *, the system does the following:

Procedure

  1. The messaging system verifies that the entered digits contain the same number of digits as the number of digits that are administered on the messaging system for extension lengths.
  2. If you restrict call transfers so that calls can be transferred only to administered subscribers, the messaging system also verifies that the digits entered match the extension number for an administered subscriber.
    NoteNote

    When callers request a name addressing transfer, the name must match the name of a messaging subscriber (either local or remote) whose extension number is in the dial plan.

  3. If Step 1 is successful, the messaging system sends a transfer control message that contains the digits to the Communication Manager server.
  4. If Step 1 is unsuccessful, the messaging system plays an error message and asks the caller to try again.
  5. The Communication Manager server verifies that the entered digits match a valid extension in the dial plan.
  6. If Step 3 is successful, the Communication Manager server completes the transfer, disconnects the messaging voice port, and sends a "successful transfer" control link message to the messaging system.
  7. If Step 3 is unsuccessful, the Communication Manager server leaves the messaging voice port connected to the call and sends a "fail" control link message to the messaging system.

    Then the messaging system plays an error message and asks the caller to try again.
