**Important**

* The fax number must contain numbers only, e.g.: 0041447873071 . Spaces and special characters are not allowed in this number.
* After the fax number there must be a space, the rest of the line gets used as a subject.
* You can also insert a list. The numbers must be separated by a semicolon ';' such as: 0041447873071;0041447873072.
* As a sender's adress the e-mail must include an adress that you have registered in the list of allowed sender adresses in the personal settings.
* In the menu option 'Settings: Access via e-mail' the check box 'I allow messages to be sent via my eCall account by e-mail' must be activated.
* You have to write the telephone number in the international format. Example for Switzerland: 0041 or +41

**Note**

* The capitalization of the recipient's identification doesn't matter.
* If there are more recipients: <faxnumber1>;<faxnumber2>; ...).
* The message being sent to the fax machine is composed of the e-mail's subject box (without fax numbers), the text box and the optional attachment.
