ABSTRACT:
A voice gateway (18) in a telecommunications network (1) includes a plurality of telephony port modules (102). Each telephony port module (102) receives telephony voice signals from a public switched telephony network (13). Each telephony port module (102) includes one or more digital signal processors (110) that perform one or more processing functions on the telephony voice signals. A particular telephony port module (102) may receive a telephony voice signal and use its associated digital signal processor (110) to process the received telephony voice signal or transfer the received telephony voice signal for processing to any digital signal processor (110) on any telephony port module (102). Telephony signals may also be transferred for processing to digital signal processors (110) on another voice gateway (18) in a voice gateway system.
