Google Voice calls dropping

I updated to to latest firmware.  Yesterday I was on a phone conversation and it kept disconnecting after 5 minutes or so...  it kept doing this.  Any suggestions on how to fix?

I also get occasional disconnects while talking on GV, though not at specific time intervals, just randomly it seems...
I wonder whether it is somehow related to the occasional GV call failure reported here: http://www.obitalk.com/forum/index.php?topic=2516.0
