So, I thought to once again look at the prices offered by various betamax providers so that people can choose the cheapest one. Below is just the rate comparison, to know more about these betamax providers just visit the respective blogpost.
Jumblo : It is offering very cheap rates to India and I guess the cheapest these days.
1 Euro cent to Indian landlines and .7 cent (less than one cent) to call Indian mobiles. SIP support is also there.
SmartVoip : It is offering the same rate of one eurocent to both Indian mobiles and landlines. So if you call landlines most then SmartVoip is equally good.
ActionVoip : It is offering 1 eurocent to Indian mobile but for lanlines it is cheaper than above two. Actiovoip charge .9 cent/min to call Indian landlines.
Webcalldirect: And many others are offering about 2eurocent/min to call India. I guess above three are a good options. If you have no other problems in using betamax then prefer Jumblo, Actionvoip over others.
Cheers to Voip !!
