Hi everybody,
I implement two Cisco SX20 units at two sites. When trying to place call between two units, it's unstable. Particularly, sometimes the call is connected, sometimes it's not connected although ping, tracert are Ok. It's very strange. I'm sure that SX20 unit works well. So I make a conclusion that there's a problem with my network but I don't know the reason exactly.
Has anyone faced this problem before?
