Phone-in and remote guest problems

Caller or guest hears an echo or themselves - They need a clean feed (also called mix-minus): the programme without their own voice. Check the phone or codec channel is set up to send it.

Feedback or howling - Turn the studio monitor speakers down or off while mics are live. Guests on a phone should use the handset or earphones, not speakerphone.

Remote guest audio drops out (codec, Zoom or similar) - Ask them to use a wired connection rather than Wi-Fi, close other programs, and use headphones. - Have a backup plan, such as calling them on a phone line, ready before you go live.
