"If you are often abroad and want to keep in touch with
friends, family and business associates back home, then you should
consider StarHub's new, affordable and convenient pay-per-use IP
telephony service Digital Voice FlexiTalk. With Digital Voice
FlexiTalk, you get free incoming calls and pay only 3 cents per
minute for outgoing calls to Singapore, both applicable wherever
you are in the world. This service also benefits your Singaporean
contacts, as they are charged at local call rates when they call
you, regardless of your location in the world."

One of my friends got this to use in Sydney while she was
working here for a year. Wondering if anyone else has tried
this out? I think I'll get it when I'm back in May!
