External telephone
In this menu, you can create and
configure external telephones
(external devices). External devices
are SIP-2.0-compatible terminals,
PC software from external manu
-
facturers or analogue telephones of
a telecommunication system con
-
nected via an SIP-ATA adapter, which
can be linked to the Access system
(e.g. VoIP table-top telephone which
is integrated via the telephone
system and which is called in the
event of an incoming call by the
Access server).
In contrast to SIP audio/SIP video
telephones registered directly at the
Access server, an external telephone
is not directly logged into the Access
server, does not receive an internal
direct dial device number and
consequently cannot be rung from
the Access server, only over the call
number of the higher-level user. The
connection takes place exclusively
over the entered telephony route
(direct dial via the local telephone
system or an external connection to
a different location) and not over
the network itself (example: If a user
is called, the standard telephone at
home should additionally signal the
incoming call).
Important!
For connection of telephones, a call
number plan for these allocated call
numbers and a gateway set up for
at least one telephone system or
one telephony gateway are required
(see
Telephony connection >
Gateways
menu).
A
Prefix
must be assigned to each
gateway. A gateway can be created
and configured in the
Telephony
connection
>
Gateways
menu.
A prefix should be a number or
number combination which is not
used for internal calls in the Access
system. It is also possible to enter
individual complete external call
numbers in the call number plan
which you wish to explicitly allow
or block.
