link did number -->pbxes.org-->voipcheap-->UM mobile

After lots of trial and error, I did finally figure out how to remotely change call forwarding on the free version of PBXes, i.e., to get call following. So this would make it possible to give friends a single US number (or whatever other DIDs you obtain), and to use that number to reach whatever SIM card you put in the phone. Both incoming and outgoing calls would be at VoIP rates, plus the cost of a local call on a local SIM chip.

It's possible to do that without pbxes. Just point the DID to the SIP address of the provider chosen to forward the call.

I tried this with IPKall and VoipCheap, but for some reason the forwarding didn't work. A call to the DID rang the VoipCheap softphone, but, if I recall correctly, I always got a busy signal when I tried to forward the VoipCheap line to another number.
