Call Waiting
Description
While in conversation, a call waiting tone informs the user of another incoming call that is
waiting. He or she can answer the second call by disconnecting or placing the current call on
hold. Call waiting tone can be enabled or disabled by dialling the appropriate feature number
or by pressing the call waiting button (refer to Button, Flexible). Either way, you can select
tone, Off-Hook Call Announcement (OHCA), or no tone.

executes Busy Station Signalling.
