GSM/UMTS phones with UMA client can use WiFi to communicate with the MSC/HLR elements in the network. The client just needs an IP connectivity to the GAN controller. So the requirement for the traditional gsm Um interface is void in this scenario.

Holger, You hit the nail right on the head ! Is there any way you have this test phone available ? It's very frustrating doing anything useful with the UMA phones out there, this test phone you are working on is it software based or a modified hardware ?
