Look-Ahead Interflow (LAI) enhances Call Vectoring for call centers with multiple ACD locations. With LAI, call centers can improve their call-handling capability and agent productivity by intelligently routing calls among call centers to achieve an improved ACD load balance. This service is provided by ISDN D-channel messaging over QSIG or non-QSIG private networks, virtual private networks, or public networks. LAI is also supported on SIP trunks. The receiving Communication Manager can accept or deny interflowed calls sent by the sending Communication Manager.

LAI has the following basic attributes:

• Produces First in First Out (FIFO) or near-FIFO call processing

• Includes enhanced information forwarding, that is, codeset 0 user information transport
