Fring's client will connect better to most SIP services than a raw SIP client. The same with Nimbuzz. I think they transcode your connection. I think it is proprietary to them and then SIP from them to your Asterisks box. Additionally, Gizmo5 will sell you an "OpenSky" connection for $20 per year which will allow you to put your Asterisks box on Skype.

The easiest way to try UMA is to buy a TMobile US prepaid SIM and UMA compatible phone. TMobile prepaid work on UMA. It is not a great deal for someone in Hungary, but won't break the bank if you are an experimenter.

I think this would be a great product for one of the roaming SIMs to offer. I don't know what the backend equipment costs, but UMA works well.
