As IP communications begin to dominate enterprise network architectures, organizations require solutions that interwork with legacy equipment and applications, including the Public Switched Telephone Network (PSTN). With 3Com® converged networks, enterprises can deploy digital or analog gateways in specific contexts to mediate control signaling, handle calls and facilitate access to the IP trunking network service. Gateway operations and service are controlled by 3Com VCX™ platforms using the Session Initiation Protocol (SIP).
3Com VoIP Gateways are designed for networking PBXs or providing aggregated connectivity to the PSTN. 3Com Analog Gateways support devices such as 2500-sets and fax machines. Both types of gateways help enterprises easily access the benefits delivered by a converged network—lowered communications and system administration costs, increased user productivity via integrated IP communications and strengthened customer interactions through advanced IP-based services.
