We use two UT Starcom WiFi phones in our UK office, and one hardwired Samsung.

The quality of call on the hardwired phone is excellent, but the two UTs are pretty much usless.

Our typical bb speed connection is between 4 and 5 Mbps. Although we often send large files by email, the bad quality calls happen most of the time, but particularly in the afternoons.

We are using a standard Belkin Wireless Moden/Router.

Is this a common experience? Or is there something we are missing in the set up.
