Designed as cost-efficient devices, they provide convenience and great savings for companies needing to place frequent long-distance and international business calls.

Cost Saving and Investment Protection. The DVG-5004S/DVG5008S gateways provide an easy and inexpensive upgrade to Internet telephony while allowing users to retain their existing telephone and fax equipment. They protect and extend users' past investments in telephones, conference speakerphones and fax machines, as well as to control their migration to IP with a very affordable and incremental investment.

Convenient Call Features. The DVG-5004S/DVG5008S support extensive call features, allowing the service providers to offer these functions to their subscribers. Provided that the telephone sets at the end-users side support these functions, callers can take advantage of these convenient features. Configuration of individual phone connection is easy using the multi-language Interactive Voice Response (IVR) or the web-based user's interface. Shared Broadband Internet Connection/Integrated 4-Port Switch. The gateways provide a convenient router function to permit office users to share the Internet broadband line.
