Panasonic KX-TC1891B - Manual (Page 59)

While You are Using a Line
During a conversation, if two tones sound and the other line status icon
on the handset display and the other line button on the base unit flash
quickly, an incoming call is being received on that line. You can answer
the second call while holding the first call. You can also make a call
without terminating the first call. If you subscribe to a Caller ID service,
the second caller’s information will be displayed when a call is being
received on the other line (p. 38).
You may delete the two tones {incoming call tone) by programming.
See page 67.
