Preface
Thank you for your confidence in us!
LANCOM Business-VoIP-Routers offer innovative all-round solutions that
integrate data and voice applications with basic PBX functions in a single
compact device. The range of interfaces available enables a LANCOM
Business-VoIP-Router to provide connections for ISDN or analog telephones,
and fax machines. The LAN interfaces allow additional SIP telephones or
softphones in the internal network to be connected up as well.
LANCOM Routers provide PBX functions via Voice over IP, making them a
technically mature alternative to conventional ISDN PBXs. They are ideal for
smaller companies, branch offices and telecommuters. Even if the Internet
connection should fail, calls can still be made to the PSTN via an ISDN or
analog interface. What's more, internal SIP users can be called from landlines
by using standard telephone numbers. In this way, home offices and smaller
sites can be cost-effectively equipped with a standardized telephony system
based on SIP.
