Currently I'm using Rynga.com to place my calls to India and some other free destinations like Thailand, Singapore, USA, etc., I bought a LinkSys PAP2T and hooked it with the Router and configured the Rynga account in it. So I can easily place the calls using a cordless phone. What you people are using?
I use VOIPbuster and localphone for custom accessnumber to each contact -- makes life a lot easier (slightly more expensive than voipbuster).
Check with either smartvoip.com or rynga.com Lot of free countries for 10 Euro (4 months valid) and also it is the cheapest one to place calls to India.
They are very famous betamax products. Betamax prices are very cheap and the quality is nice. But the rate is not reliable. They may raise the price per minute at any time (but that too for sure cheaper than the other providers) without any prior notice. At the same time, they introduce new website with new brand name with much cheaper price also. So always I go with 5 or 10 Euro credits with them.
I don't make calls too often because I can almost see and talk to everyone online but for those times I need to make calls especially if its international calls then I use my VoIP service with Onesuite.com. The thing I like with Onesuite is it's a prepaid service. Means, I don't waste minutes if I don't use it like those monthly plans with 500 minutes or so. So I don't pay anything if I didn't use it.
I also have PAP2T for my Onesuite VoIP account and it works great. Linksys together with Grandstream have good and reliable ATA devices.
You need a Skype phone to do that. And you don't connect it to a land "line", you connect it to your internet line like cable or DSL thru modem or router.
