Introduction

For a while now, smartphones have been established as an alternative to mobile phones and have developed into genuine multi-functional units. In addition to mobile accessibility, there is also focus now on the use of additional applications and services – both on the move as well as in the office or at home.

In doing so, however, data security must not be compromised. The safest way of connecting mobile workers and devices to the office or home network is a virtual private network (VPN). A VPN is like a shielded tunnel which connects the sender and recipient. Outsiders do not have access to this tunnel. Data and e-mails can be exchanged in such a secure manner between mobile devices, i.e. an iPhone in our example, and the local office or home network of the elmeg hybird 120™. The VPN tunnel ensures the secure connection of the iPhone/iPad to the elmeg hybird 120™ from a public WLAN hotspot in a hotel, from a private network between business partners/friends, or directly from the mobile network.

Thanks to suitable improvements, i.e. through so-called apps, mobile and landline telephony can be merged into a single device on smartphones. This is described in an additional workshop entitled Connecting a smartphone as an internal VoIP telephone. Via an existing VPN connection between the iPhone and the elmeg hybird 120™, the iPhone can also be remotely connected as an internal VoIP telephone to the elmeg hybird 120™. The iPhone is also registered as an internal VoIP telephone on the elmeg hybird 120™ by the appropriate app via the VPN connection and can be involved in the communication, just like any other connected telephone. Internal calls are just as possible remotely as the use of external landline connections, such as the configuration of an activated ISDN connection in the office

The advantages include the following:

This workshop describes how to set up a VPN IPSec connection between an iPhone/iPad (referred to in the workshop as an iPhone) and the elmeg hybird 120™. In doing so, only the settings required for this scenario within the elmeg hybird 120™ as well as on the iPhone app shall be explained. Other possible settings are not included in this workshop. The elmeg hybird 120™ and an iPhone 4™ were used in this example. Other devices with similar software versions can be configured in an identical or similar manner.

The GUI™ (Graphical User Interface) is used for configuring here.
