Zoom Releases Major Enhancements to Internet Telephony Products

Zoom Technologies , a leading provider of communications products since 1977, today announced major on-board software enhancements to its ZoomTel(TM) Voice over the Internet (VoIP) product line, including the Zoom X5v and V3. The X5v is an ADSL modem with built-in VoIP, router, 4-port switching hub, and firewall. The V3 is similar, but substitutes an Ethernet port for the ADSL modem to enable plug-in operation with a separate DSL modem, cable modem, or an Ethernet network.

Zoom began shipping its critically acclaimed VoIP products in the second quarter of 2004. The new firmware features add the capabilities that Internet phone service providers have most frequently asked for, including Quality of Service (QoS), STUN support, and other enhancements.

The Quality of Service feature means that the ZoomTel hardware prioritizes voice data packets over other packets so that voice quality remains high, even when there is substantial non-voice traffic.

STUN is a protocol used by service providers to reliably deliver voice traffic through a NAT firewall or router. STUN would typically be used when the Zoom V3 is placed behind a separate NAT firewall (i.e., not the V3's) in a home or office.

"These are important improvements to our award-winning VoIP product line," said Frank Manning, Zoom's President and CEO. "Some of our major customers have been waiting for these improvements, and we are now positioned to significantly grow our revenues in the VoIP market."
