A broadband connection allows VoIP-channel organization to communicate with the RSG module. To the RSG unit can be connected to digital station or a regular phone, and it is possible to connect an ordinary analogue trunk. Thus, the remote worker has access to all functional possibilities the main PBX, as well as any other user.

If there is not one or more members as a remote segment, but a branch, it is not a problem to make sure that no employee of the branch did not feel cut off from the main office. Telephone exchanges are connected through the channels on IP-based networks and become, as it were a single entity, with a single numbering plan for internal and sharing functions.
