When I put our SX50 in night mode, all external calls go to cordless. But, when a call comes on the cordless, I can hear the caller, but the caller can't hear me. So, I have to go to run to the console, take it out of night mode and hang up on the caller, hoping that they call back. I have tried switching out cordless phones and putting night mode to different extensions but the problem persists. Any ideas?
