Ideal for the office and everyone who makes a lot of calls, the is an affordable, yet powerful SIP business telephone with built-in full duplex speakerphone and three-party conference bridging. A 2 x 24 semi-graphical LCD display and a menu-driven user interface supports easy feature management. 12 programmable keys with LEDs support flexible identity access/key configuration. A 100 number call memory, a 100 entry onboard address book (to which data may easily be uploaded), custom call blocking, configurable/ downloadable ring tones, auto-answer mode, DND and other sophisticated features ensure convenience and productivity. And the ’s built-in web server supports even simpler end user configuration, screen dialing, and access to call history. The is remote-manageable and firmware-upgradable, uniquely easy to install, and largely self-configuring. Broad codec support and full compatibility with current SIP recommendations ensure interoperability; support for STUN (NAT traversal), ENUM (for dialed-number resolution) and other state-of-the-art features enables flexible deployment behind local proxies, IP PBXs or hosted VoIP services. The supports the security standard SRTP – a current specification from the Internet Engineering Task Force (IETF) for protection against eavesdropping – and TLS for protection against sniffing of signaling and authentication data. By limiting the need for external conference bridges/media server capacity or use of conference services for routine multiparty calls, the ’s built-in three-party conference bridge helps limit total cost of ownership, while also ensuring high audio quality and low latency.
