The Cisco SPA303 IP phone is in stock.

The 3-line SPA303 connects directly to an Internet telephone service provider or to an IP private branch exchange (PBX). A few of the features include dual switched Ethernet ports, built-in high-quality microphone and speakerphone, 2.5mm headset jack, caller ID, call hold, conferencing, call transfer, call pick up and park, call blocking and call forwarding. Other basic features include directories, call timers, call logs, speed dialling and multiple ring tones. 

It has a 128×64 pixel monochrome graphical LCD screen, easy installation and highly secure remote provisioning, as well as menu-based and web-based configuration and it supports both SIP and Smart Phone Control Protocol (SPCP) with the Cisco® Unified Communications 500 Series. This enables a quick rollout of a feature-rich business phone system.

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 SPA 303. The SPA 303 supports productivity through VoiceView Express, and Cisco XML applications (when interfacing with the Cisco Unified Communications 500 Series in SPCP mode). 

There are highly secure options including password protection and encrypted authentication to protect your system.

We provide a one year warranty with every business telephone and part sold. We stock a large stock of new, remanufactured and refurbished office telephone system spares and phone parts, and deliver worldwide. Please quote product code SPA303 when ordering.
