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.
• Configured prefixes (country prefix and local area code)
The PBX offers the callback option to an external caller if their call is not answered.
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.
Charge information
Requirements:
• Charge information provided by the network provider
The PBX stores the charge information sent by the network provider and uses it to evaluate
individual calls.
Important:
Disabling this function is only advisable if it causes problems on the external
connection (this depends on the network provider/country).
Some telephony providers do not send charge information. If this type of
provider is being used, you cannot apply any charges to a particular call.
Notes:
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.
