I can't believe this hasn't been asked before, but I di search for it - honest!
I can configure Zoiper OK with one of my providers (voiphone) but they charge 12p ($0.20) for calls to mobiles. I have a Nimbuzz Out account which is only $0.05 for mobile calls, but I can't find the server settings I need to use Zoiper (a better app than the Nimbuzz one) with my NimbuzzOut credit.
Is it possible?
Thanks
