METHODS AND APPARATUS FOR CONTROLLING CALL PULLBACK BY AN AUTOMATIC CALL DISTRIBUTION (ACD) SYSTEM FROM AN INTERACTIVE VOICE RESPONSE (IVR) SYSTEM AND FOR ALLOWING AN ACD CALLER TO COMPLETE A CRITICAL TRANSACTION WHILE CONNECTED TO THE IVR

摘要

Methods and apparatus for controlling the ability of an ACD server to pull back a call from an IVR server and for allowing an ACD caller to complete a critical transaction while connected to an IVR include special processing and network signaling which enable the ACD to set a pull back status flag and grant permission to the IVR to request a change in the pull back status flag. An exemplary protocol and message encoding are disclosed.
