Integration of Funkwerk PBXs in existing LAN Infrastructure

Task

In many cases it is useful to integrate a PBX into an existing LAN. The advantages include the use of the existing LAN network for VoIP telephony (phones and soft clients) and the configuration of the PBX or polling of fee data from any PC. Here the existing router must be in a position to manage the voice traffic and also to prioritize voice data. It should also include an additional ALG (SIP proxy) for external VoIP calls. The requirement for implementation is that the router manages the LAN and WAN operation, while the PBX is restricted to operating the classical and VoIP end devices.

Task

Suitable PBXs include the elmeg systems ICT, T444 and T484. These PBXs are configured and integrated in the LAN in such a way that the router component in all PBXs is not activated. In this case, the VoIP phones and soft clients obtain their IP address from the existing router, but log on to the PBX via the phone. IP system telephony is even possible in the existing LAN with the use of an elmeg ICT. SIP providers can be logged on to the system for external VoIP calls. In order to ensure the best possible transmission of voice and data, if in doubt, we recommend replacing the the existing router with one of our R series routers.

Benefit / Highlights

Advantages of PBXs with LAN connection

Registration with VoIP providers and support for VoIP phones in the LAN
Configuration / management of the PBX can be carried out from any PC in the LAN
Status messages in the control center to every PC in the LAN
IP phones are seamlessly integrated into the existing call number structure

Advantages of routers

Routers are responsible for Internet access (incl. firewall) and LAN management
Specific broadband management possible: Load balancing
Through IPSec VPN security: No possibility of unauthorized eavesdropping or recording

The VoIP-VPN gateway module supplements the elmeg ICT systems. It unifies Internet telephony (VoIP) with secure data exchange over VPN. Two integrated slots for DSP expansion modules additionally provide the VoIP-VPN gateway with digital, highly compressed voice channels for transition into the PSTN.
