Linksys SPA942

The SPA942 has been discontinued by the manufacturer. The replacement product is the SPA504G.

Please Note: This is a PoE capable device and the AC power adapter is not included.

Four active lines and dual switched Ethernet ports offer incredible flexibility to the home or small-business Internet telephony user. 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
