I've gone for the other end of the scale and i have gone for the cheapest provider that i could find.
However, if they were unreliable i would have left, but after using only voip indoors for 18 months, i have never had a problem with localphone.
The owner used to own ebuyer, but decided to venture into voip. (i think thats correct)
Calls are from 0.4ppm to call uk landlines and 1.5ppm to call a mobile.
The service has been perfect for me.
Also, make sure that you buy a phone that can stop the sip scanners.
My sister had problems last week and luckily, the phones settings was able to stop the phantom calls that can happen.
Good Luck. I doubt there will be any going back to pots.
edit - additionally, be very careful, voip fraud could end up being a nightmare. I choose to use payg for all my accounts, just in case.
