Call charge information
Issue 5 October 2002 1531555-233-506
■ Call Transfer
For Advice of Charge, if a transferred call is routed over a public-network
ISDN-PRI trunk group, AOC administration for the outgoing trunk group
controls whether AOC information is requested or recorded for the call. If
two or more outgoing trunks are connected together via trunk-to-trunk
transfer, the Avaya MultiVantage may receive AOC information from the
network for each outgoing trunk involved in the call.
■ CDR Adjuncts
Avaya MultiVantage does not tandem AOC information through a private
network to other switches. Therefore, the CDR adjunct that records AOC
information must receive its input from Avaya MultiVantage directly
connected to the public network.
■ CDR Call Splitting
If you use CDR Call Splitting for outgoing trunks, each time a call is
transferred, the system generates a separate record. Attendant Call
Recording, a form of Call Splitting, generates a CDR record when an
attendant drops from a call. Incoming Trunk Call Splitting has no effect on
charge information.
If you rely on Call Splitting or Attendant Call Recording, you should
request call charge information during the call. However, for AOC, this
increases message activity on the signaling channel and reduces Busy Hour
Call Capacity of the MultiVantage System.
In some countries, or with specific protocols, AOC information during a
call is not available. In this case, you can use the Elapsed Time in the CDR
records to allocate the charges among the parties on the call.
You must use CDR Call Splitting if you want the charge display to restart
at 0 when a call is transferred.
■ Centralized Attendant Services
In any configuration where a branch system has no direct connection to the
public network, the private network does not pass call-charge information
to these branches.
■ Conference
If a user adds a third party to a call in charge-display mode, the display
returns to normal. Call charges will not appear as long as there are more
than two parties on the call.
■ Distributed Communications System (DCS)
In any configuration where a branch system has no direct connection to the
public network, the private network does not pass call-charge information
to these branches.
