Here is an example of how a
trunk line
can be established or simulated:
1. First, the
Trunk Line
PBX object with the E.164 call number
0
and the H.323
name
Exchange
must be created.
2. On a free ISDN interface (PPP, TEL, BRI or PRI), you enable the H.323 regi-
stration and allocate the name of the of the
Trunk Line
object (Exchange) or
the call number (0), as well as the IP address of the gatekeeper on which
the PBX is operated. It is also sufficient to specify the local IP address
127.0.0.1
if the gatekeeper happens to be operated on the same device.
The interface must have successfully registered with the PBX object and
calls to the
Trunk Line
PBX object must be possible. A dial tone is played at
this point only with a connected ISDN trunk line. Suffix dialling digits are
accepted.
3. To simulate a dial tone for least cost scenarios, for example (see also the

example: Subscriber A calls subscriber B. Subscriber B for-
wards the call from subscriber A to subscriber C.
The CGPN (

call diversion. Merely the DGPN (

umber) is
also sent as information, so that both call numbers are visible
at the diversion destination (subscriber C). For an external call
diversion to the PSTN, it is not permitted to use an external
CGPN (subscriber A), however. Therefore, the CGPN must be
replaced by an associated call number, in this case the DGPN
(subscriber B). If this check box is not enabled, the local tele-
phone office, in such as case, will automatically replace the
CGPN through „screening“.
If you enable this check box,
the diversion call is signalled
as a normal outgoing call.
The CGPN is then a number that
belongs to the connection (subscriber B).
