The CALL module is located between a board physical layer (ICS/MPR/ALC)
and a H.248 protocol module. The CALL module is designed to shield the
protocol module from connecting to the physical layer directly, enabling
the protocol module to be transplantable. The CALL module also can shield
the protocol layer for boards. The module can be consistent with interfaces
for protocol modules as MGCP and H.248.
