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.
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
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.
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.
