Due to office refurbishment and systems upgrade I have 14 Cisco SPA502G IP Phone's and a Polycom Soundstation 2 for sale. All in used condition, excellent working order. Ideal for any new start up organisation or for those wishing to add to their existing phone network. Happy to sell individually or as a set £15 per unit with free postage. **WILL ACCEPT OFFERS** See below for Technical Details: Description Part of the Cisco Small Business Pro Series, the SIP based Cisco SPA502G 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 SPA502G 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 SPA502G. The Cisco SPA502G 1-Line IP phone also supports productivity-enhancing features such as VoiceView Express and Cisco XML applications when used with Cisco Unified Communications 500 Series in SPCP mode. Carrier-Grade Security, Provisioning, and Management The Cisco SPA502G uses standard encryption protocols to perform highly secure remote provisioning and unobtrusive in-service software upgrades. 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.
