VoIP
My home phone has been ported to VoIP. We beta-tested Voicepulse for about three months; everything went fine, so we put in to have the port done. Any calls to our home number will now be digitized, packetized, fragmented, routed, and then reassembled automagically. Or so they say.
Let me know if you sense any problems with your calls. Of course, if IP traffic is really broken, you better send complaints via snail-mail.
Update:
20 Feb 2006 - a few hour outage for incoming calls. Outgoing calls unaffected. Customer support was pretty quick about this, buy saying only that the problem was with their "upstream service provider".
