1.12 Holding Features

1.12.1 Call Hold

Description

Conditions

•	Using the Call Hold feature, a PT user can have one intercom call and multiple outside (CO) line calls on hold at the same time. To hold multiple intercom calls, the user should use the Call Park feature ( 1.12.2 Call Park). Using the Call Hold feature, a single line telephone (SLT) user can have either one intercom call or one outside (CO) line call on hold. To hold multiple calls, the user should use the Call Park feature.
•	If an outside party is placed on hold and the call is not retrieved within 30 minutes, the call is automatically disconnected.
•	Music on Hold Music, if available, is sent to the outside party on hold ( 1.12.4 Music on Hold). An internal audio source, external audio source, or tone can be selected as the Music on Hold through system programming ( Music on Hold [111]).
•	Doorphone calls cannot be put on hold.
•	Hold Recall If a call on hold is not retrieved within a preprogrammed time period ( Hold Recall Time [200]), a ring tone will be heard at the extension that put the call on hold. If the extension is engaged in a call when the timer expires, an alarm tone will be heard. If the hold recall time is set to "Disable", no tone will be heard. Going off-hook after the hold recall time has expired automatically re-establishes the conversation with the call on hold.
•	SLT Hold Mode It is possible to choose how to hold and transfer a call with an SLT, if the length of time that the Recall/hookswitch is pressed is shorter than a specified duration ( Hookswitch Flash Timing Range [207]). The following methods ( SLT Hold Mode [104]) are available:
	Mode Hold Transfer to Extension Hold-1 Pressing the Recall/hookswitch + Going on-hook Pressing the Recall/hookswitch + Extension No. Hold-2 Pressing the Recall/hookswitch + Call Hold Feature No. + Going on-hook Pressing the Recall/hookswitch + Extension No. Hold-3 Pressing the Recall/hookswitch + Call Hold Feature No. + Going on-hook Pressing the Recall/hookswitch + Call Hold Feature No. + Extension No.
	In some cases, a call is not disconnected when an SLT user goes on-hook. Instead, the call is mistakenly placed on hold. After a specified time expires, the Hold Recall tone is heard. When the SLT user answers this, the user hears a cyclic tone (like a reorder tone). To avoid this problem, select "Hold-2" or "Hold-3". In either of these modes, all calls are disconnected when going on-hook, unless the Call Hold feature number is entered after pressing the Recall/hookswitch. It is possible to set each SLT not to receive pulse signals through system programming ( Internal Pulse Detection [614]). This setting helps the PBX to avoid mistaking pulse signals sent by dialling "1" for hooking, in the countries/areas where the length of time that the Recall/hookswitch is pressed is set to "MODE 1: 50–180 ms" in Hookswitch Flash Timing Range [207].
