One aspect of the invention relates to a messaging communication scheme for controlling,
configuring, monitoring and communicating with a signal processor within a Voice
Over Packet (VoP) subsystem without knowledge of the specific architecture of the
signal processor. The messaging communication scheme may feature the transmission
of control messages between a signal processor and a host processor. Each control
message comprises a message header portion and a control header portion. The control
header portion includes at least a catalog parameter that indicates a selected
grouping of control messages and a code parameter that indicates a selected operation
of the selected grouping.
