Operation with the telephone
Contents
Commands can be triggered via telephone calls. Number codes are not required for this. The assigned command is executed by calling a target phone number. The procedure is reliable and convenient as only calls from known telephone numbers are made and the functions can be entered directly as a "name" in the telephone directory of a mobile phone.

It is possible to assign shortcut or speed-dial keys (e.g. in office environments).

Individual commands can be executed from any workplace as the target phone number and the caller's telephone number can be combined. A target phone number with voice message can be assigned to any workplace.

For example, a single target phone number for "light ON" can apply to all workplaces in an office. However, only the actuator of the workplace whose telephone number was assigned is switched.

Additional status objects (Project settings/Other) are available for further evaluation of calls.

1.Data

Designation

Designation of telephone operation in the project. In this case, you are recommended to assign a name to the calling telephone.

Workplace number

Designates the telephone number, e.g. of the office workplace, of mobile phones or telephone extensions. A call is made from this telephone number to trigger a function of the HS/FS.

The telephone number from which the call is made is entered here. The leading zero must always be replaced by an * (asterisk). For connections from abroad, it is advisable to hide the leading digits using an * (asterisk) (e.g. *2195602123).
Important
The telephone number must be transmitted with the call. Please test this by making a call to a different telephone (e.g. mobile phone).
Note
The system list debug page contains the section "Telephone operation", here you can see which call is coming in while the HS/FS is in operation.

Answer

Yes: The HS/FS accepts the call by answering it and executes the command. The HS/FS answers immediately and returns a busy tone.

No: The HS/FS accepts the call without answering it and executes the command. After 2 rings a busy tone is emitted.
Note
Answering takes only a small amount of time and is recommended for applications with a large number of users (e.g. open-plan offices).
Important
This option is ignored if the caller calls a target number with a voice message.

Buttons

The target telephone numbers and commands are managed in this list.

2.Voice message/DTMF

Apply

Yes: Relays a voice message when a call is answered.
No: No voice message is relayed.

Target No.

The calling number. If this number is called from a workplace, the voice message is played.

Voice message

After the connection has been established, the voice message set here is played. This voice message can be dynamically exchanged. For this purpose, the voice message (see below) is changed. This can be used to create an acoustic menu using the DTMF keyboard, for example.

Pause (in sec.)

Pause between the voice messages. The time which elapses between the voice message and repetition of the voice message.

Voice message duration (in sec.)

The time in seconds in which the voice message is played. If this time has elapsed without a telephone button being pressed, the connection is terminated by the HS/FS.

DTMF object

If a voice message is running, the HS/FS can evaluate the DTMF button codes of the telephone. The button code is written to the selected communication object. The communication object assumes the following values when the following buttons are selected:
  • Button 1-9 => Value 1-9
  • Button 0 => Value 10
  • Button * => Value 11
  • Button # => Value 12
Note
On activation of the 1st button, first a 0 then the button is sent!

Status object

The status information of the current alarm call is written to the selected numerical communication object:
  • 1: Dialling.
  • 2: Connected and voice message is started.
  • 3: Voice message ended

Voice message object

The voice message can be dynamically influenced by changing these variables (see also the information on voice message above). For this, the 14-byte communication object specified here must be written with a valid voice message key.
