LANCOM 1724 VoIP

The VoIP routers LANCOM 1724 VoIP feature two LAN and four ISDN
interfaces, making them ideal for establishing larger SIP telephone
infrastructures that feature up to eight parallel ISDN channels for incoming
and outgoing calls to the public telephone network.
To operate in this mode, all 10 of the DIP switches on the underside

of the LANCOM 1724 VoIP must be in the down position! Set the DIP
switches 1 to 4—supplied ex-factory in the up position—to the down
position.
Before altering the DIP switch settings, remove all cables from their
sockets and switch the device off.
