Many people use Internet Phone, such as Skype, to talk internationally across the net, but both must have the same software and fast connections. For more info, visit: Google's Directory on Internet Telephony or Yahoo's Directory on Internet Telephony.
"I recommend scheduling a certain time each week that you *may* call home. I chose early Sunday morning (home time) so as to catch someone at home. If there were any important messages, I could pick them up that way." <Alan Nelson>
"Do not assume you can place your call and get through at all times. Some countries have very few external circuits and they are often busy for long periods. Do not assume you can use touch-tone equipment to communicate with the US end (answering services, etc.) even if you carry a touch-tone beeper with you. You may be able to reach the answering service (and pay for that call), only to find that the international circuit is not good enough to work properly. This varies widely from country to country and from day to day." <Larry Cotter>
