Stimulus signalling protocols and message protocols are methods for transferring information over a communications network. Stimulus signalling protocols (e.g. P-Phone) are typically used for connecting simple terminals to a more powerful host whereas message protocols (e.g. H.323 standard) are typically used to connect between such hosts. Equipment has typically been developed and manufactured for use with either but not both systems and this has led to the need for protocol conversion devices which are complex and time consuming to develop and maintain. Voice data is sent via an H.323 channel over a data network and associated P-Phone signalling data is sent via a T.120 channel as part of the H.323 call. This enables stimulus signalling protocol equipment (e.g. business telephony handsets) to be used in message protocol systems without the need for protocol conversion.
