Hi, you'll probably need to provide more details, like which version are you on, how are you connected to the PSTN, etc.
Also, when it doesn't work, what happens, just silence? If so, if you stay on the line and eventually speak to an agent, can they hear each other? Basically, is it "only" the menus that don't work when it is a bad call?
