Call-in
Extracted from the Wikipedia article Phone-in.
In broadcasting, a phone-in or call-in is a programme format in which viewers or listeners are invited to air their live comments by telephone, usually in respect of a specific topic selected for discussion on the day of the broadcast. On radio (especially talk radio), it is common for an entire programme to be dedicated to a phone-in session. On television, phone-ins are often part of a wider discussion programme: a current example in the UK is the "Jeremy Vine" TV show.
