A signalling switch for use in information protocol telephony is provided, which can initiate, sustain, and terminate a plurality of discrete voice and data calls simultaneously. A plurality of cards are mounted on a computer bus, where the first card is a single board computer whose function is to act as the operations and maintenance control card for the switch. A non-system card functions as a message transport controller card; and there is at least one further non-system card which functions as a master application controller card. Local bus communication among the non-system cards is provided by a local bus found on the message transport controller card. Telephone routing information protocol software is resident in the switch, and the switch communicates externally via Ethernet interfaces. Thus, the signalling switch may be positioned in an information protocol telephony network environment to initiate, sustain, and terminate connections between a client and the network or the network and a client, under the control of the resident telephone routing information protocol software.
