The callback function is an important eWON feature to enhance security and reduce costs of remote maintenance.

The callback function requires an external action which is for example:

• a pre-defined number of ring on the eWON phone line
• a login to the eWON and a callback request

When the Callback function is activated, the eWON returns a call to a pre-defined phone number.

The Direct Callback function calls a classic phone number and performs a point-to-point connection basically to a PC configured as 'Incoming Call Allowed'.

The Internet Callback function calls a local ISP (Internet Service Provider) and publishes its Internet TPC/IP address by email (to a pre-defined email address) or using a Dynamic DNS services such as www.no-ip.com
