6.4.1 Configuring Busy on Busy
This feature rejects an coming call if you're already in an active call on either the phone or Skype
for Windows client. It plays a busy signal to the caller.
To configure Busy on Busy:
1. Access the Call Waiting screen (MENU key > Settings > Call Waiting).
2. Select the Busy on Busy option.
