What is the best way to make phone calls back home?
There are a variety of calling card options, although VOIP (Vonage, Lingo, Skype, others) are the most popular choice at present. Having a U.S. number makes life so easy for family and friends back in the U.S. Most U.S. government housing has a PBX system in the house. Most PBX systems don't have instructions as to the features. Many of the systems in the housing pool do not pass caller ID or other modern features to the extension phones. If you're going to us a VOIP box and like seeing caller ID, consider bringing a two-line cordless phone system with you, and just put the other phones in the closet. - Jan 2008
We use Skype. Telmex has outrageous rates for normal land line calls. - Jan 2008
