ZoomTel V3 Router/Gateway/Firewall/4-port Switch plus VoIP
The V3 integrates a router, firewall, four-port 10/100 Ethernet switch, USB port, and VoIP analog phone adapter into a single cost-effective product.
The Model 5577 TelePort™ feature provides a phone port that lets you use your standard single-line phone for conventional phone calls or free and very low-cost Voice Over IP (VoIP) calls*. Because the V3 integrates Internet telephony with a full featured gateway, setup is easy and system security is ensured. Integration of the voice processing with the firewall in the router ensures reliability of VoIP calls and reduces service provider support requirements.
The V3 uses SIP (Session Initiation Protocol) for compatibility with a wide range of VoIP infrastructure equipment.
The Model 5577's built-in four-port Ethernet switch eliminates the need for a separate Ethernet hub for most home networks and many small offices. The USB port allows direct connection of a fifth computer to the V3. By adding external hubs or a wireless access point, the V3 can provide simultaneous Internet access for up to 253 computers.
The V3 can also be connected to a regular phone line in addition to a broadband connection. The Local Phone port of the Model 5577 includes the TelePort, an intelligent relay that allows a single phone to place and receive both VoIP calls and calls over the Public Switched Telephone Network (PSTN). PSTN Fail-Over allows the Model 5577 to automatically route calls over the dial-up phone network when power is lost. PSTN support also allows emergency dialing using services like 911 or 112 calling.
Setup is easy using any authorized local or remote computer's Web browser and the graphical user interface built into the V3. After setup, V3 voice features work even without a computer attached. Flash memory allows easy firmware updates, including additions to the voice compression codecs. The integrated VoIP terminal adapter can be configured remotely using a TFTP download from the VoIP service provider.
The V3 is built and supported by Zoom Telephonics, a publicly-traded company (NASDAQ:ZOOM) with over 27 years of experience in telephony and data communications.
