[asterisk-users] Recommend quality wholesale termination - Singapore and Sydney, Aus

[MFH]

Can anyone recommend decent quality as close to pay-as-you-go SIP 
wholesale termination providers in both Singapore and Sydney, 
Australia?  I will be in both places and want a local carrier while I'm 
there.  It needs to be easy in and easy out and if it's not $0 base or 
close I'll need to be able to drop it in a month.
