I have Clear Wimax wireless internet (Clearwire) at a couple locations. I typically get at least 3-4Mbit download and 1-1.5Mbit upload on speed tests. At both of these locations I hear the caller just fine but they often complain of a broken sound. Sort of garbled and dropping out, but generally useable. I ran a test on the connection at one of the voip websites and the results were that the jitter level was near the limit. Is there a way to adjust the under hood settings in the Obi boxes to improve the performance? I think that a bit of additional latency would be fine if that is the tradeoff.
