Seems like a very crowded scene. So few of these products/projects actually reach the limelight.

So, can anyone explain how Joe Ordinary User can connect a phone to his computer, using OSS programs, and make free VOIP calls to land lines?

ubuwalker31: Nerd Vittles has several excellent guides for setting up an asterisk server, connecting a standard telephone, and connecting to the PSTN via "free" sip carriers. Of course there is no free lunch, but this is about as close as it gets. You will need to supply a PC and buy a telephone interface (SPA-1001 can be found around $60). The "free" carriers will require you to put $10 or so into the account.For windows (CentOS running in VMware)<a class="user" href="http://nerdvittles.com/index.php?p=152">http://nerdvittles.com/index.php?p=152</a>For Intel Mac (CentOS running in VMware) <a class="user" href="http://nerdvittles.com/index.php?p=165">http://nerdvittles.com/index.php?p=165</a>For linux (the same CentOS)<a class="user" href="http://nerdvittles.com/index.php?p=153">http://nerdvittles.com/index.php?p=153</a>

zRTP works very well, but only can be use with Softphones (needs to be running on the PC running the softphone/client). It's by Phil Zimmerman (who did PGP). <a class="user" href="http://en.wikipedia.org/wiki/ZRTP">http://en.wikipedia.org/wiki/ZRTP</a>
