Cisco SPA921 1-line IP Phone with 1-port Ethernet

I bought this phone hoping for a reasonably priced SIP phone to use with my Asterisk box at home. I was unimpressed with this item. First, the screen is NOT backlit like the Cisco/Linksys manual states. I'm using it in a fairly dark area and really need the backlit display. However, the biggest problem was that I experienced one-way audio with all incoming calls. I've set up quite a few SIP phones and am quite familiar with the "one-way audio problem" as it relates to NAT (network address translation). However, all of my test calls were on a local network. No NAT was involved. I have several SIP hard phones and soft phones installed with no one-way audio problems at all. I gave it two stars because it feels like a solid phone and reminds me a lot of the higher-end Cisco phone I have on my desk at work. The phone has been returned and I'll pick out a different brand.

I purchased this product and compared it with other SIP phones of similar price. [$70-$120]. Featuring a truly simple web-based configuration, I didn't need to read any documentation except to find the default password to get this phone up and running with my small < 50 users Asterisk (using freePBX) deployment.The audio quality is excellent, and the construction feels solid as well.If you need extensive features, you will have to spend more on a different model, but if you just need a simple 1 line IP phone on a budget this is a great fit.

Works awesome with my gizmo5 account.The down side is that now that cisco merged the linksys support site into the cisco side of the house finding documentation, new firmware, etc is a total nightmare. Also there's no documentation on setup in the box and cisco's support site is horrible, so just google search for how to set it up.
