Call waiting
Network requirements
As shown in Figure 71, place a call from Telephone C to Telephone A which is already engaged in a call
with Telephone B, and the call will not be rejected. Just like a normal call, the subscriber at Telephone C
will hear ringback tones, while the subscriber at Telephone A will hear call waiting tones, as a reminder
that another call is waiting on the line.
