I recently visit to Nepal. I was very surprised by the internet phone commonly known as E-Phone in Nepal.

You can make call from nepal to US for Rs. 2/min from any cyber or communcation place which offer Ephone service.

after some research i bought a VOIP device from vonage and connect it on my router ( u must have cable internet dialup aint work and extra telephone set)  

now my parents can call me from nepal and pay only Rs. 0.64/min which is obviously cheaper that making local call in ktm.

if you need more information about how to setup E-phone in your house in nepal feel free to drop me email on adhikaribipin@hotmail.com

take care
