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

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) leaders, enabling service providers to quickly roll out competitive, feature-rich services to their customers.

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.
