Assigning Trunk Groups
Connections of the same type and in
the same direction are arranged in a
trunk group (e.g. S
0
multi-terminal
connections). To be able to correctly
transfer incoming calls to the mem-
bers of the configured companies
(the users) via the lines of a certain
trunk group of the OpenCom 510,
each of the available trunk groups
must be assigned to one of the com-
panies. This is necessary to be able
to transfer incoming external calls to
the correct company exchange in
cases where the called internal sub-
scriber cannot be reached (“Connec-
tion to Operator”), for example.
The assignment of trunk groups to
companies is done in the
PBX Configuration: Trunks: Bundle
menu
.
For outgoing external calls which us-
ers set up via the lines of their com-
pany’s trunk group, the assignment
of the trunk group to the company is
irrelevant: the charges are assigned
according to the “source” principle.
Charges are billed to the company to
which the user belongs who set up
the connection. The OpenCom 510
recognises this on the basis of the
assignment between user groups
and companies and on the basis of
the routing code with which a line of
the trunk group was seized. For
more information, please see the
following section.
Allocating Routing Codes
Routes are used for automatic and
selective seizure of trunk groups or
connections for external calls. It is
possible to seize a route by predial-
ling a code.
In the
PBX Configuration: Trunks:
Route
menu, you can define which
company can seize each route. An in-
dividual
code
for the seizure is allo-
cated per route for each company.
The OpenCom 510 ensures that dur-
ing configuration no seizure code is
allocated twice (for two different
routes) for each company. If during
configuration of a route no code is
allocated for one of the configured
companies, the route concerned
cannot be seized by the members
(user groups) of this company.
Configuring the Company
Exchange
An internal telephone number must
be set up for each company which
represents the exchange, i.e. “the
operator”. The calls to specific exten-
sions arriving at the exchange are
routed to this number, for example,
as are all external calls where the
called subscriber (a user who be-
longs to this company) cannot be
reached, as in the case of a timeout.
