Exact Channel Mapping - NEC Univerge SV8100 Installation Manual

Exact Channel Mapping

MyCalls uses a best effort matching system to tag calls in the recorded calls database with calls in the
MyCalls database. In some circumstances MyCalls cannot guarantee to correctly match the correct
call in the two databases. In order to get around this problem Exact Channel Mapping can be used.
Exact Channel Mapping is recommended for sites that take a large number of calls on one particular
DDI or where multiple Call Recording units are used. Exact Channel Mapping works simply by each
trunk number in MyCalls being mapped to its corresponding ISDN channel number. Where multiple
call recording units are being used, each unit must be given an ID (CSID.) Where exact channel
mapping is used and configured correctly, the match rate will be 100% accurate. If it is incorrectly
setup all calls will be incorrectly matched.
Single BRI Unit
With a single BRI unit, there are 4 things to consider relating to Exact Channel Mapping. These are
the Unit ID, the Port Number, the ISDN Channel Number and the PBX Trunk Number. All of these
items will need assigning to enable Exact Channel Mapping. By default every Call Recorder will have
a Unit ID of 1, further information on checking and changing the unit ID is provided later in this
Technical Publication. The Port Number is the physical port that the Call Recorder is connected to.
The diagram below shows how the ports are numbered. The Channel Number is the ISDN Channel
Number; this will be 0 or 1 dependant on whether the call is on the first or second ISDN channel
respectively.
In MyCalls go to the Configure / Telephone System / Edit PBX and edit the Call Recorder
