A scalable call management system. The system can include at least one voice server hosting one or more voice browsers, the voice server having a single communications port through which voice call requests can be processed by the voice browsers, each voice browser having a port alias through which call requests can be processed. The system also can include a call processing gateway linking telephony endpoints in a public switched telephone network (PSTN) to the voice server. Finally, the system can include a translation table mapping port aliases to respective voice browsers.
