The LANCOM VoIP Call Manager upgrades LANCOM routers with powerful Voice over IP functions which offer professional data and voice communications.

Available as the VoIP Basic Option and VoIP Advanced Option, the Call Manager is suitable for all current devices labeled as "VoIP ready". Along with internal and external VoIP communications, these options enable the ISDN interface to be used for switching telephone calls between internal VoIP subscribers and the public telephone network.

More flexibility.
The VoIP Call Manager supplements LANCOM routers with the functions SIP proxy, SIP/ISDN gateway and call router. These features enable a seamless transition between ISDN telephony and Voice over IP in a huge diversity of scenarios. For instance, various accounts at SIP providers can be used on a shared basis, and upstream VoIP PBXs can be integrated, too. By way of the router’s ISDN interface, the Call Manager enables SIP terminal equipment to call ISDN subscribers in the public ISDN telephone network. The automatic number translation and the conversion between SIP and ISDN are completely invisible to the user, and migration paths can be planned flexibly.

More quality.
The VoIP Call Manager can optionally intervene in the negotiation of voice compression for VoIP connections. This allows certain coding methods to be dropped in favor of other methods which offer better quality or optimize the use of available bandwidth. In combination with the excellent Quality of Service functions, the best possible voice quality can be achieved. The availability of telephony can be assured both by the all-round redundancy functions of the LANCOM router and by reverting back to the alternative ISDN lines, if necessary. This ensures that, even when using VoIP, levels of availability can be guaranteed to satisfy professional scenarios.

More Benefits.
The VoIP Call Manager provides professional levels of redundancy and security from eavesdroppers—benefits which are based upon the VPN and load-balancing functions in LANCOM routers.

All functions are integrated into the central management functions. Configuration and monitoring of the voice functions are fully integrated into LANconfig and LANmonitor and can also be accessed via SNMP, SSH, Telnet and the web interface. This provides uniform management of PBX and IP components, which leads to a reduction in administration effort overall.
