LANCOM 1722 VoIP – LANCOM 1724 VoIP
Chapter 1: Introduction
When the telephone structure is extended with a LANCOM VoIP Router, a
variety of new possibilities become available for connecting telephone termi-
nal equipment. This includes the existing analog or ISDN telephones (where
necessary, connected to the respective PBX) or VoIP terminal equipment such
as SIP telephones or PCs with VoIP software.
As a new and central building block in the telephone structure, the LANCOM
VoIP Router assumes many of the PBX tasks for connected terminal equip-
ment. As such, you can also set up the automatic outside line access for the
terminal equipment connected to the LANCOM VoIP Router directly for the
ISDN or SIP subscriber groups, thereby adapting it to existing telephone
behavior.

gain access to an outside line - that is, to carry out a telephone conversa-
tion via a public telephone network.
Without the "0" prefix, the number dialed is considered to be an internal
number from another extension line on the private PBX.
If "automatic outside line access" is set up, all numbers dialed are directed
over the public telephone network. In this case, internal telephone calls to
other extensions are not possible or only possible when a special symbol
is dialed before the number.
When automatic outside line access is turned off, subscribers must dial a
"0" before the desired number in order to carry out a telephone conver-
sation via a public telephone network.
All calls without a "0" preceding the number will be treated as calls to
internal extensions within the private telephone network.
If automatic outside line access is turned on, all numbers dialed will be
directed over a public telephone network.
For telephone calls to internal extensions, a special symbol or a specific
number combination must be dialed before the number. With the stand-
ard settings, when automatic outside line access is enabled, a star * is
activated as the identification symbol for an internal number. This setting
can be adjusted to match the character that you are familiar with.
If you operate the LANCOM VoIP Router on the extension line of a
PBX, it is recommended that outside line access for the router be con-
figured in the same way as for the PBX so that the behavior remains
the same from the user's perspective.
