Remote Programming
Proceed as follows:
• Using the Configuration Manager (page Administration > Remote configuration)
ARA PIN
The ARA PIN is required for the following purposes:
• As a PIN for remote programming from an external phone (e.g. for enabling remote configuration or switching the alarm on/off)
* Note: To change an existing PIN, click on  Edit PIN.
* Note: All the PINs in the PBX are unique. For this reason, you cannot assign the same PIN twice.
* Note: Do not use dates of birth or dates as PINs. This makes it easy for an attacker to find out the correct PIN. Do not use PINs which are easy to guess, such as 111111 or 123456.
* Caution: Visible PINs are a security risk.
• After you enter your PIN, click on  Hide PIN.
Remote switching number Tel. no.:
Requirements:
• External numbers have been entered
---: no remote switching number.
The remote switching number is required for the following purposes:
• As a PBX phone number for remote programming from an external phone (e.g. for enabling remote configuration or switching the alarm on/off)
* Note: If no remote switching number has been entered, you must dial a character string on an internal phone to unlock the PBX for remote configuration. After this, the PBX can be accessed via every associated MSN/DDI number.
* Note: You cannot use call forwarding to divert this phone number.
* Note: You must select the DDI number to be sent for a PTP connection from the extensions block. If the DDI number is then displayed in red text, either it is not in the value range, or the maximum number of external phone numbers has already been entered.
