Integration of a Remote Subsidiary via VoIP

An increasing trend towards using home offices is apparent in many companies. Besides field service staff, for reasons of flexibility, part-timers in home offices are increasingly connected with their company headquarters. The aim is that these employees can work just as though they were employed in the central office. This gives rise to numerous advantages, e.g. integration in central office teams, ideally busy status information of all integrated staff, a unified company number to the customer, telephone cost billing via the central company connection, central phone book and not least the strict separation of private and company connections. It is advantageous that this solution does not require any intervention in the existing phone infrastructure at the external site. Many of these advantages are also of relevance to small company branches with a maximum of 1-2 extensions.

Another advantage is that data can be communicated with the central office via secure VPN connections. This should also include the option of voice prioritization for phone calls.

An R series router with IP phone can be used in the home office. This IP phone logs on to the FEC PBX directly and is therefore completely integrated in the system. This facilitates the standard telephony functions, such as call waiting, call back, call transfer, 3-party conference between central office and home office.

The busy status of the IP phone is also displayed on the system phones at the central office. If an elmeg ICT system with the internal VoIP-VPN gateway is used, IP system phones can be integrated via a VPN tunnel. The home office then has the full functionality of a system phone at the central office, e.g. busy information for all subscribers and the central phone book.

If an elmeg ICT system is used or an R series router at the central office, the voice connection and data connection, which is also possible, can be rendered even more secure using a VPN tunnel with the highest encryption. In both cases, settings are possible to improve the voice quality and for dynamic broadband management (QoS).
