Durable, Affordable, Feature-Rich IP Telephone for the Home Office and Business

• Small, affordable, single line business class IP Phone

• Connect directly to an Internet telephone service provider or connect to an IP PBX

• Wall mount of table top phone

• Easy installation with secure remote provisioning.

Comprehensive Interoperability and SIP-Based Feature Set

Based on the Session Initiation Protocol (SIP), the Cisco ® SPA901 1-Line IP Phone (Figure 1) has been tested to ensure comprehensive interoperability with equipment from voice over IP (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 SPA901 addresses the requirements of traditional business users while building on the advantages 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 of the SPA901.

Carrier-Grade Security, Provisioning, and Management

The Cisco SPA901 uses standard encryption protocols to perform secure remote provisioning and unobtrusive in-service software upgrades.
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 time and expense of managing, preloading, and reconfiguring customer premises equipment.
