This item is the SPA-941 model, which has been sold under the Sipura, Linksys, and Cisco brands. It is a fully featured SIP standard phone that is compatible with Asterisk, and it works through NAT. Before Sipura was liquidated, they published firmware that unlocked most of the extra-cost features, like certificates and multiple line registrations. Ensure that you upgrade the firmware to get these valuable goodies. The spa941-5.1.8.zip file is the latest and probably last release. Advanced features like certificate registration and automatic provisioning seem to be very difficult to configure, so I run these phones with manual configurations. It's just easier to use the web configuration interface than to figure out the XML magic. If the SPA-941 gets the same ease of integration with Asterisk VOIP systems as the Polycom product family, then I will upgrade my rating from 4/5 to 5/5. This Amazon SKU comes with a power supply, so you don't need the extra part that Amazon recommends.
