Abstract: This invention relates to an intelligent peripheral (IP) for connecting to a telephone network and providing added capabilities to the network. More particularly the invention relates to programmable suppression of call answer supervision by an intelligent peripheral or a voice recognition unit in a telephone network. The method comprises the steps of: the peripheral device receiving a call setup message from a network switch when a call is being initiated. The IP, on receipt of the call setup signal, suppresses the normal answer signal output and instead outputs a progress signal to the network switch. For an ISDN network the progress signal is a Progress Indicator PI=08 signal.

Abstract: A voice processing system 60 is connected via a digital trunk line 100 to a telephone switch 10, which is itself connected to a telephony network 30 by a digital trunk line 20. The digital trunk line between the switch and the network uses a first encoding law for representing the amplitude of the telephony signals, for example A-law encoding. However, applications running on the voice processing system are designed to operate on signals encoded in accordance with a different amplitude-encoding law, for example mu-law encoding. The voice processing system therefore includes in a telephone interface module 70 conversion means for converting incoming signals from the first encoding law to the second, and vice versa for outgoing signals.
