The DVG-6004S/DVG-6008S VoIP gateways can be deployed to interface VoIP infrastructure with a Public Switched Telephone Network (PSTN). They allow analog callers to place calls through the long-distance Internet trunk line. The gateways accept dial tone and ring current from the connected equipment, and facilitate the use of conventional phone sets and fax machines on a VoIP network.
Guaranteed Voice Quality. The DVG-6004S/DVG-6008S gateways deliver clear sound, voice, and reliable fax calling by implementing internationally recognized standards for voice and data networking. They incorporate Quality of Service (QoS) functions to ensure that the voice received through the Internet is the same as or surpasses that received on the ordinary phone.
