Hello all, I'm not sure to explain this in detail, but here it goes. I use an ASUS RT-N16 at home as my router, with Tomato firmware. 1.27.9044 MIPSR2-beta07 ND USB Ext I am able to connect my T-Mobile Shadow cell phone, and make UMA calls. This saves me a good bit of minutes. At work I have a mix of ASUS RT-N16 and WL500 routers set up as access points. My Shadow is unable to make UMA calls when connecting to any of these access points (5 in total). I don't remember the exact firmware image on the routers at work. I think they're close to the same image as my home device. I'm wondering what configuration I may have missed that makes UMA non-functional at my workplace. Any ideas?
