VoIP-ISDN BRI Gateways

Introduction

Majority of the organizations have an existing investment made in their ISDN infrastructure. While low-tariff IP telephony has emerged as a viable alternative for long-distance calling with the IP network wide-existent. It is therefore necessary for the businesses using ISDN PBXs to provide VoIP connectivity to their users. This allows the users to select the IP networks to make and receive calls for obvious benefit of cost. Also, reaching other network transparently by interconnecting helps eliminating the huge interconnection charges and thereby saves significantly on call costs.

The VoIP-BRI gateway that offers integrated interfaces for VoIP and ISDN BRI networks. The gateway can be scaled from 2 to 32 BRI ports. A single VoIP card provides up to 32 simultaneous channels. These modular gateways come in varied configurations, with built-in support for multi-port Auto Attendant, in-depth Call Records, DDI and Least Cost Routing.

Matrix ETERNITY works as an adjunct to your existing telephony infrastructure. There is no need to replace any equipment like PBX, Operator Consoles, Key Phones, Standard Phones, Power Supply and Wiring. This not only saves lot of equipment cost, but also saves time and efforts required for re-training.

Calls can be seamlessly routed between VoIP and ISDN networks. Fixed or Least Cost Routing can be selected to decide route for an outgoing call. It can handle calls on all the ports simultaneously allowing full traffic on all the ports. The elaborate routing algorithm encompasses different attributes like Port, Calling Number, Called Number and Time. It selects the most cost-effective route for a given number at specified time. In addition, it allows the flexibility of reserving ports for important users. Numbers dialed can be translated by Automatic Number Translation (ANT) feature to match with the destination network.

International Calling is another big opportunity for saving hard-earned money. VoIP calling provided by Internet Telephony Services Provider (ITSP) is much cheaper when compared with regular fixed and mobile lines. Matrix ETERNITY offers VoIP connectivity with multiple ITSP servers giving flexibility of using separate ITSP for each country/region like USA, Europe, etc. VoIP can also be used to provide free calling between different locations of a company – head office, branch offices, factories, warehouses, etc.

Matrix ETERNITY VoIP-BRI Gateway is very easy to install and operate. Built-in web-server allows the system engineer to configure various parameters locally or remotely using any Internet browser.
