The TVP-221H VoIP Gateway is an H.323 Standards Compliant Gateway with 4 analog telephony ports (2 FXS and 2 FXO) allowing for up to 4 concurrent voice connections. This combination of analog telephony ports gives users the flexibility of making direct VoIP calls via analog phone/fax device or through PBX/CO lines respectively. Features Supports up to 4 channels of real-time concurrent voice and / or fax communications. Field programmable CP tone detection and generation to support PBX and CO line interconnections. Supports programmable line interfaces with country specific telephone settings. Supports ITU standard voice codecs and voice processing algorithms including G.711 G.723.1 and G.729 A/B and G.168 Echo Cancellation as well as Fax T.30 and T.38 Intuitive management interfaces (Web Telnet and Console) ensures rapid deployment / reduces demands on MIS resources. Network administrators can remotely monitor and perform routine maintenance / trouble-shooting via Internet browser or telnet session. H.323 standard v.3 compliant (including H.323 fast-start mode) ensure interoperability with 3rd Party H.323 Standards Compliant Devices. Supports IP Precedence prioritized Voice before Data packets providing best effort QoS Built-in TFTP and Flash memory for firmware download and upgrade via network Support Call forwarding and Call Transfer Supports Dynamic IP/ PPPoE client support Supports DHCP client support Supports Dynamic DNS for deployed in a dynamic IP environment Bulk Call successful rate over 99.98% Recommend to use with dedicated broadband connection 5-Year Warranty Technical Specifications Telephony Interface Physical interface Desktop with 4 Analog Ports?
