Settings – Public switched tel. networks
ISDN connections
You cannot check exactly how many PBXs should be charged for each
call because, for example, you cannot uniquely assign the charges to
one of the two subscribers involved in a query call from an external call.
If you are using the Soft-LCR 4.0 LCR procedure, the duration of the call
and your own table of tariffs are used to calculate the charges.
CCBS
Requirements:
•
Service feature CCNR (callback on no response) is enabled by the
network provider.
•
Configured prefixes (country prefix and local area code)
The PBX offers the callback option to an external caller if the
connection they dialled is busy.
Important:
If this function is enabled, but the network provider does not support it
(service feature not unlocked), it might still happen that the caller is given
the option of a callback. In this case, the caller's reply is not forwarded
to the PBX and therefore the function cannot be performed.
In addition, this function can often only be used if both call partners are
using the same network provider.
CCNR
Requirements:
•
Service feature CCNR (callback on no response) is enabled by the
network provider.
