    • A method of reducing an audio gap in a connection between communication hardware and a mobile unit during a handoff between a first cell and a second cell in a communication network, wherein a first voice processor is communicatively coupled to a mobile switching center that services the first cell, is disclosed. The method includes the steps of determining when the mobile unit is likely to move from the first cell to the second cell, establishing inbound and outbound communicative coupling between the mobile switching center and a second voice processor that services the second cell when the mobile unit is likely to move from the first cell to the second cell and determining that the mobile unit has moved from the first cell to the second cell.
