Hi there Sometimes in a conversation the other party or me just misses a milisecond of what the other said. It is when the other party or me just had a small silence. I know from my Fritzbox AVM that you can switch this data-saving option off and on. Can you switch this certain function on or off in the 3CX phonesystem? It is a little irritating to ask all the time to the other party what he just said. And what is the official name for this function.
