This issue unfortunately came back...although now with significantly fewer people being affected. Right now we have about a dozen tickets about it compared to hundreds last time.

We have some people testing a workaround to stabilize things as we work with Grandstream on this. If you'd like to help with that, here is info: http://forums.voipo.com/showthread.php?p=8960#post8960

We appreciate everyone's patience. I'm confident this will be resolved shortly and service levels can get back to normal.
