I have been using internet telephony for the last 1 year with skype. Among the various providers of dirt cheap calls skype is the best and cheapest way to talk Its voice clarity is much better than yahoo or net2phone the ability to make calls to us in 1 rs a minute against the 7.5 rs u have to pay for landline is simply unimaginable my two brothers have been living in the us for quite some time and in order to talk to them i talk freely without worrying of the bill coz for the money i pay i can talk for 45 mins paying just 45 rs instead of 45*7.5 rs.
