Help Mytouch-4G with Bluetooth over WiFi = audio problems?

[Bga123]

I have a stock MyTouch4G paired with Plantronics Voyager Pro. When on a WiFi call, after about 8 min of use the call begins to break up on the headset. Switch to speaker phone and the call is clear. Any idea what might cause this or a fix? I also tried a second Plantronics Voyager headset and experienced the same problem.

Has anyone else experienced problems with Bluetooth audio when on WiFi connection?

The issue for me is that wi-fi calling isn't as consistent as regular dialing. The connection you have is solid?
