VoIP
The VoIP Adapter (SIPAdapter from sipphone.com) finally came! All I had to do is plug in RJ45, RJ11, and the power cord and everything was up and running. 
The default “white noise” is little bit different from the POTS so it’s little unnerving… Also, the phone automatically downloads new configuration from central TFTP server, meaning I cannot set any personal settings. I guess I can override it, but I’ll wait for now until I get more familiar with it.
Just waiting for my aunt to setup the phone so that I can actually try it with real service. ^^
