ISDN Primary Gateway

The Primary Gateway delivers a cost effective, reliable and secure Voice over IP capability for legacy telephony equipment equipped with Primary Rate ISDN interfaces. Designed to satisfy the demands of carriers and enterprise networks alike, it has an extensive list of features that make it one of the most flexible and reliable boundary call routers for professional use.

Alternative IP Carriers: The compact unit is easily installable due to its “in-line” position in an existing ISDN PRI trunk line and its ability to be configured directly through IP or through the ISDN line from the remote management platform. No configuration or extra trunk cards are required in the PBX and no user training is necessary.
Enterprise Networks: The Primary Gateway can be used to provide an easy path to VoIP (Voice over IP) connectivity between multiple offices and individual home based workers. Calls between offices can be invisibly diverted across the existing enterprise IP network or the internet to provide considerable savings on call costs.

Reliable Connectivity: Automatically allowing calls to fallback across multiple routes, the Primary Gateway ensures that calls connect even under severe network problem conditions, guaranteeing the highest level of connectivity.

True Convergence: Equipped with two Ethernet ports the Primary Gateway also provides IP routing between an internal IP LAN and an external IP WAN. An integrated DHCP server and NAT capability means the unit can provide both voice and data connectivity to a site in one unit. The IP WAN connection can be a leased line, Wireless LAN, Satellite or any other permanent IP connection.
