Hi Alex, So if you're sending data out there is no or almost no data loss?
Have you tried to move the VM to the second host to see if it makes any difference? I actually tried to call you by phone but the call gets dropped once I enter * and your ext. number, as the voice prompt says to. Tried to enter the ext. number directly without *, still without success.
