I have had my Airave 2 for over a year now and it has mostly been working well, up until recently. Lately, when people call us on our Sprint phones (iPhone 4s's) while we are at home using the Airave, the calls are (with increasing frequency) breaking up and/or making our voices sound sort of robotic to the folks on the other end. Strange, I realize, but I called my wife from work the other day and heard what others had experienced. Anyone else with the same issue? Thoughts, suggestions?
FYI, I did the 8x8.com test and it passed Sprint's minimum requirements with no problems.
