What authentication are you using none, mac on AP or Mac on radius?

You will have audio drop if you are using MAC on radius because of the time for authentication. I personnally took off authentication and setup a separate non-routed VLAN for my voice/spectralink traffic. I would also look at how much overlap I have on my AP's your device may be trying to authenticate to too many Ap's

On a recent installation, we had terrible voice quality problems with CallManager-controlled Spectralink phones associated with AP1200s. The wireless LAN was in great shape for all other devices, and everything else like the SVP server was in good order.

We then set the "Data Beacon Rate" (DTIM) to 2, in accordance with Spectralink's recommendations. Everything started working well. I cannot tell you much about what that parameter is or does, but it worked for us. If you search Spectralink's website, there are PDF documents with recommended settings for various Cisco access points.
