Same as I did for my voip service when I had it. call quality is great when on UMA. My problem is the fact that the phones will switch between UMA and GPRS very often during the day. Half the time I take the phone out and look at it, I am on GPRS in the house. when only the wifi connection is on, I can keep UMA connection 100% of the time in 100% of my house, and when going outside I can keep the connection pretty much to the outskirts of my 1/2 acre property. When I have both the wifi and mobile networks connections active, I will UMA and GPRS switch on and off in the house, and whenever I leave the house only GPRS.
Does the phone automatically switch to the STRONGER signal, or is it only when the wifi signal gets to a low enough strength that the cell signal picks up?
Are there any settings that I can play with or check on the phone/router to make sure that the UMA stays connected better? Right now I am keeping the mobile connection off while in the house and only turning it on when I know I am leaving the house....

I don't know anything about the Zyxel router but see if you can change the Fragmentation and RTS Thresholds to 2304. I've had pretty good luck with these settings on my DD-WRT flashed Linksys router. My router wouldn't constantly drop off and on the network until I changed these settings. I hate to say it and you probably won't believe me bu its probably a setting with the router that is causing this.
Another suggestion is to upgrade the phone from 4.5.0.52 to .69. I can't tell you were to get it but it is out there. Try it and see what it does for you because for me it sped up the connection process to my wifi network and UMA works quite flawlessly compared to .52.
You shouldn't have to swap off and on the mobile network either. I can leave my house and when the signal of the wifi gets to weak it transfers the call over to Edge really quick.
