NEC Univerge SV8100 SL1000 - Single BRI Unit; Single Analogue Unit; SIP Trunk Call Recording

Single BRI Unit
The same concept applies to Basic rate, with a single BRI unit to assign a Unit ID, Port number and
Channel Number to a Trunk Number in MyCalls. Unless multiple units are being used, the unit ID will
always be 0. The port number is always the same as the channel number.
With Basic Rate ISDN the Channel Numbers run sequentially from 0-7, channel 0 will be trunk 1,
channel 1 will be trunk 2 and so on.

Single Analogue Unit
Assuming the trunk numbers run sequentially from 1-8 then the channel mapping would be configured
as follows.

SIP Trunk Call Recording
In order to use channel mapping with SIP Trunk call recording, you must have SV8100 R4 software or
above installed on the SV8100. Slightly different to the way channel mapping works on ISDN
recording, when a call SIP call is made, the trunk number that the call is made on is stored in the
Sense database. MyCalls can then match calls using the trunk number is was made on. SIP calls
always has a fixed Unit ID of 129 that cant be changed. If many SIP trunks are connected to one call
recording PC then then unit ID will always be 129 and the Port and Channel will always be the same
as the trunk number. Some examples are shown below:
