Voipcheap.co.uk / Voipcheap.com

[MAN WHO]

I've been using voipcheap from voipcheap.co.uk for a while now and its great for my girlfriend calling her family in Poland.

But I noticed today that there is also a site called voipcheap.com that seems to be the same program but with different call rates. (eg poland is free)

A quick whois check revealed that these 2 sites are registered by the same company - Betamax GmbH & Co. KG

Anyone know if these programs are identical?

Maybe I should switch to voipcheap.com to get the cheaper rates to poland
