Call Waiting
(in Web UI)
Description	Allows you to enable or disable Call Waiting on the IP phone.
	If you enable call waiting (default), the user has the option of accepting a
	second call while currently on the first call. If you disable call waiting, and
	a user is currently on a call, a second incoming call is automatically
	rejected by the phone with a busy message.
	If you disable call waiting on the phone, and the user is on a call, any
	further incoming calls will receive busy unless “Call Forward Busy” or “Call
	Forward No Answer and Busy” is configured on the phone. It will then
	forward the call according to the rule configured. The phone can only:
	• -transfer the currently active call
	or
	• accept transferred calls if there is no active calls.
	If call waiting is disabled:
	• on the 57i CT base, and the handset is currently on a call, all additional
	incoming calls are rejected on the handset.
	• intercom calls are treated as regular incoming calls and are rejected.
	• pre-dialing with live dial pad disabled still accepts incoming calls.
	• the “Incoming Call Cancels Dialing” parameter is ignored because the
	incoming call is automatically rejected.
	• the Missed Calls List does not get updated with details of calls.
	• the Blind Transfer feature on the phone may not work if two calls are
	made to the phone at one time.
