My intention is that that the costs of the TeleService session is
billed to the plant und therefore I would like to be called back
after dial-in. How can I do this and what must I take into
The costs of the phone call are normally billed to the person that
starts the TeleService session. However,TeleService can be used in
the sense that the modem connection is shortly established for the
first contact. Afterwards, the reverse/opposite direction is
established by the TS Adapter (call back). Now, the costs are
allocated to the plant.
TeleService distinguishes between 2 call-back variants:
- Call back of a phone number which is indicated during the
This Variant is favorable if the costs for the modem connection
should be billed to the plant or if the actual call-back number is
variable. The call-back is not always intended to be directed to
the same recipients number. Thus, this is interesting for users who
- Call-back to a phone number which is predefined in the TS
This is the variant with the highest access rights protection. It
might imply the risk that a wrong configuration of the TS adapter
might lead to the danger that a modem connection can be
unreachable. This circumstance might require a field service on the
Prerequisites for both variants are access protection,
information regarding the site as well as dial-in
configuration using the integrated TS adapter function in
"Extras > in the TS adapter parameterize adapter properly".
Important for both call variants is that the correct
information regarding the site and the dialling
properties are inserted. The TS adapter uses this configuration
to call back together with the call-back number. Particularly
important are prefix, dialling procedure and the
call setting "wait for dial tone before dialling".
With the prefix you can configure the behaviour of the TS
adapter on site, e.g. with a "0" you can indicate, that the modem
is connected to a telephone system. With the "0" you can get
an outside line and with "," you will wait 500ms before the actual
phone number is dialed. Using the modem at a main extension
just by changing the location of the TS adapter and removal of the
entry in the field prefix. If you proceed as described here then
you can enter the call-back number in both call-back variants as
follows: "089 32 168".
By configuring the access protection you can determine the
|Call-back to number provided at dial-up
|Call-back to a number deposited in the TS adapter
If a wrong call-back number is deposited by the administrator
"ADMIN" then the TS adapter is not remotely accessible.
- Do not assign a call-back number for the administrator "ADMIN",
respectively before doing this test the call-back number with a
user, then assign this one to the administrator.
- Test the call-back number with "at dial-up define phone
2) The call-back number can be stated at a dial-up. A
here provided phone number has got a higher access protection
priority and cannot be overwritten.
3) A call-back number can be changed by the
respective user. This must take place before you change the
