SPA942 4-Line IP Phone with 2-Port Switch
Four active lines and dual switched Ethernet ports offer incredible flexibility to the home or small-business Internet telephony user. Formerly part of the Linksys Voice System (LVS), now part of Cisco Small Business IP Phone Series, the SPA942 IP Phone can be configured to carry a unique phone number or extension for each of its lines, or can be configured to use a shared number over multiple phones.
Based on the SIP standard, the SPA942 is able to easily integrate new features and services offered by providers. A high-resolution display makes for easy menu- and web-based configuration.
Additional features of the Cisco SPA942 IP Phone include:
- Power over Ethernet 802.3af, allowing for single-source electricity without an additional power supply.
- A high-resolution graphical display; dual switched Ethernet ports; high-quality, full-duplex speakerphone; and a 2.5 mm headset port.
- The ability to connect directly to an Internet telephone service provider or to an IP PBX.
- Easy station moves, presence, and shared line appearances across local and geographically dispersed locations.
