We have an area where we have folks using Ascom phones which the reports we are getting are that the phones worked much better before they were lightweighted. We have the controller setup per Ascom's recommendation and have worked extensively with Ascom but have yet to be able to get these phones stable. Before the upgrage they had a very dense environment and the APs were all cranked to full power. Looking back through the configurations before the upgrade there were some of the APs that did not have the Ascom WLAN on them so we went through created an AP group without Ascom on it to make it so that essentially the same APs had the Ascom WLAN on them but still had the same issues.
I understand the concept that the Lwapped APs are doing a tunneled connection back to the controller and the path is pretty simple as the path goes:
AP===>3560=====>6513=====>6509=====>6513 VSS Pair where the WISMs are installed and the Ascom voice gateway is on that same VSS Pair as the Wisms.
Anyone ever involved with these phones in a lightweight environment that might be able to give some pointers?
