Operation as a PBX
In many cases, LANCOM VoIP Routers can completely replace a local PBX.
With up to eight voice channels (e.g. LANCOM 1724 VoIP) to landlines, the
possibility to use SIP accounts and SIP trunking, and the data- and voice net-
working of various sites, these are powerful and future-ready alternatives to
conventional PBX systems.
A systematic set of instructions for setting up the LANCOM VoIP Router for this
purpose can be found in the PBX Funtions manual. Beforehand, we recom-
mend that you read the following chapters on the basic setup of devices and
software, and then carry out a basic configuration. You should also have set
up the Internet access before you continue with setting up the PBX functions.
Supplementing existing PBXs
VoIP functions can be conveniently added in to existing telephone structures
by using a LANCOM VoIP Router. The LANCOM VoIP Router is simply con-
nected between the public exchange line (e.g. ISDN NTBA or analog tele-
phone line) and the PBX.
