Cisco SPA3102 Voice Gateway with Router

The SPA3102 gives you both an FXS port (for a phone) and an FXO port (for a phone line), it's two devices in one box. Each device can operate independently or can be made to interact with the other. It's great for a start-up VoIP system where you want to have one phone and access to one phone line from the PSTN. Be aware that this is NOT a device that is made for plug and play. You have to know what you are doing. It is an extremely flexible device with MANY options. Which means it can be overwhelming to a beginner. A lot of the options can be left at default but you still need a basic (at least) understanding of networking, SIP and VoIP to get this working with a provider or VoIP PBX. If you know what you are doing, this unit can be up and running in 10 minutes, otherwise you'd better have a lot of patience.

To begin with, it turned out that a D-Link router on my network had the same IP address for configuration. But I was still unable to connect after I removed all other devices on my network. Finally I downloaded the administration guide from the Linksys download page for the SPA3102 device, and its "Basic Administration and Configuration" instructions described how to get the IP address using a telephone attached to the device (****110#). The second page of the quick install guide, it turns...Read more

SPA3102 is upgraded version of SPA3000 from Sipura. This device has all the cool features of SPA3000, and in addition it has a built-in router, which avoids SPA3102 not being behind any router. Secondly, it has larger memory(ROM), and enables two G.729 calls simultaneously.

All in all is truely a masterpiece.
