The AGFEO Voice-Over-IP Solution for WAN Interconnection of Existing AGFEO PABX Systems
Press Release


At CEBIT 2006 AGFEO showed the WAN interconnection of existing AGFEO PABX Systems. Retaining the existing numbering plan, this solution offers users accustomed telephony features and a considerable saving potential for companies. Internal calls between locations can be made over the Internet using cost-efficient broadband connections. Data security is guaranteed via encryption. Selected LANCOM routers with integrated data encryption (IPsec) are used for this purpose.
Using the system is as simple as can be. The caller chooses the number of the person he wants to call at the distant location. The AGFEO Least Cost Routing (LCR) will decide whether the call can be made more cost-efficient via a broadband line using a router. The LANCOM router identifies the location the connection is to be made to using the number based on the dialled number. A LANCOM router also comes into use when forwarding the data to the connected AGFEO PABX System.
If the broadband connection is not working for any reason, and no connection can be made between the two locations, the call can also be made over the conventional fixed telephone network. Both the AGFEO PABX System and LANCOM router make this decision automatically, so that the caller can still reach the person he wants to talk to in the conventional manner.

The proven SIP (Session Initiation Protocol) standard is used for voice transmission in the IP network, which also allows for the use of other Voice-over-IP components.
