Ease of Use

I've used Grandstreams, Polycom's and Aastra VoIP sets with Aasterisk/Free PBX. This set is by far the easiest to set up and configure. Great sounds and features. I will use this set exclusively for all new installations.

Product Overview

Stylish and functional in design, the Cisco SPA942 4-Line IP Phone with 2-Port Switch is ideal for a residence or business using a hosted IP telephony service, an IP private branch exchange (PBX), or a large-scale IP Centrex deployment. The Cisco SPA942 uses industry-leading voice over IP (VoIP) technology from Cisco to deliver an upgradeable high-quality IP phone that is unparalleled in features, value, and support.

Based on the Session Initiation Protocol (SIP), the Cisco SPA942 has been tested to ensure comprehensive interoperability with equipment from VoIP infrastructure leaders, enabling service providers to quickly roll out competitive, feature-rich services to their customers.

With hundreds of features and configurable service parameters, the Cisco SPA942 addresses the requirements of traditional business users while taking advantage of the benefits of IP telephony. Features such as easy station moves and shared line appearances (across local and geographically dispersed locations) are just some of the many advantages.

Standard features on the Cisco SPA942 include four active lines, dual-switched Ethernet ports, 802.3af Power over Ethernet (PoE)* support, a high-resolution graphical display, full-duplex speakerphone, and a 2.5-mm headset port. Each line can be independently configured to use a unique phone number (or extension), or can use a shared number that is assigned to multiple phones.

The Cisco SPA942 uses standard encryption protocols to provide secure remote provisioning and unobtrusive in-service software upgrades. Highly secure remote provisioning tools include detailed performance measurement and troubleshooting features, enabling network providers to deliver high-quality support to their subscribers. Remote provisioning also saves service providers the hassle and expense of managing, preloading, and reconfiguring customer premises equipment (CPE).

The power supply for the SPA942 is sold separately and is required if PoE capability is not implemented.
