VoIPCheap Free Usage Policy Exceeded Seems Random

[Distorted Vision]

I've just started using VoIP making SIP calls on my new Nokia N95 and so far I'm very impressed by the quality of calls.

However, I was looking at my VoIPCheap recent calls and I can't make sense of the FUP exceeded. There seems to be no pattern and it seems completely random. I must stress that I've only been using the service for one day so it may be because there were a few calls to the same number that disconnected as I was configuring my phone. All is perfect now but strangely it wasn't the calls all to the same number that I got charged for.

Anyway, I was wondering what the general consensus on here was about VoIPCheap and maybe you can give me some further tips.

I was also looking at getting a Sipgate account so that I could get a free geographic number.

I look forward to hearing from you. Many thanks for your help!
