Linksys SPA901

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

Comprehensive Interoperability and SIP Based Feature Set
Based on the SIP standard, the SPA901 has been tested to ensure comprehensive interoperability with equipment from VoIP infrastructure leaders enabling service providers to quickly rollout competitive, feature rich services to their customers. With hundreds of features and configurable service parameters, the SPA901 addresses the requirements of traditional business users while leveraging 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 SPA901 uses standard encryption protocols to provide secure remote provisioning and unobtrusive in-service software upgrades. Linksys 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, pre-loading, and re-configuring customer premise equipment (CPE).
