Pennytel - lower IDD rates

We're trying Pennytel (www.pennytel.com) as our main VoIP SIP provider for IDD calls, instead of Pfingo because the Pennytel rates are darn cheap:

1. *untimed* calls are 10 Singapore cents (about 6 US cents) to USA, and landlines in Australia and UK. There is also a timed plan and the per minute rates are also low.

2. calls to India are charged at 2.4 Singapore cents per minute, 60% cheaper than Pfingo

3. timed calls are billed per second, not per minute as for most other voip providers I have stumbled across

4. no fixed subscription, and no expiry of credit

5. overseas registration is no problem providing you have a credit card that will be authenticated

Hopefully the IDD audio quality and call reliability with Pennytel are as good as Pfingo...
