DVG-2032S VoIP




The DVG-2032S VoIP station gateways present an ideal Internet telephone solution for business use. These gateways convert voice traffic into data packets for transmission over the Internet, combine the industry’s latest Voice over the IP network technology with advanced communication features, and are fully compatible with SIP Internet phone services. With high port densities, they provide a low cost of ownership, convenience and great savings for companies needing to place frequent long-distance and international business calls.
Cost Saving and Investment Protection. The DVG-2032S gateways provide businesses with an easy and inexpensive upgrade to Internet telephony while allowing them to retain their existing telephone and fax equipment. These devices allow businesses to protect and extend their past investments in telephones, conference speakers phones and fax machines, as well as to control their migration to IP with a very affordable and incremental investment.
16 or 32 Internet Telephone Connections. Each gateway provides 16 or 32 FXS ports for simultaneous Internet phone connections. Plug in regular phone sets to these ports, and they instantly become Internet telephones. For businesses with frequent needs for long-distance and international phone calls, these devices provide great cost savings and convenience, while keeping configuration and maintenance to a minimal level.
Guaranteed Voice Quality. The DVG-2032S gateways deliver clear voice and reliable phone/fax communication through implementation of internationally recognized standards for voice and data networking. They incorporate Quality of Service (QoS) functions to ensure that voice received through the Internet is the same as or even surpasses that received on the ordinary phone.
Convenient Call Features. The DVG-2032S gateways 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.
