UNIVERGE SV8100

The Virtual Loopback feature gives users the ability to dial, or route, calls to the DDI routing tables by

creating DDI calls internally.

This can give additional flexibility in routing when transferring manually or 'automatically' using, for

example, single digit options from DSPDB and voice mail Auto Attendants.

Additionally, if the system is only equipped with non-ddi CO lines with CLI enabled (analogue or ISDN) it

is possible to create a DDI for the received CLI by transferring it to a loopback port.

Note: Virtual Loopback requires the configuration of Department Groups and Direct Inward Dialling (DDI)

for maximum flexibilty.

Creates a range of numbers which can be dialled internally (e.g. operator)

New number range are pointed at a DDI Table

Names appear on phone and can be reported on using call logging application

The Virtual Loopback creates up to 30 extension ports and 30 trunk ports for use as Loopback ports.

Each trunk created by the virtual loopback must be set to DID mode. The trunks are then placed into a

Trunk Group and routed to a DID Translation Table Area.

You can specify a different area for each night mode.

The DID Translation Table Area contains a specified quantity of DID Translation Entries, the received

DID number is compared to each entry to find a match.

The DID Entry will then specify the destination extension number, Incoming Ring Group, Department

Group or Voice Mail.

Each DID Entry has three destinations available, the incoming call can be made to fall over to the next

destination if the call is busy or not answered.

When viewed on PC programming it is possible to view the assigned virtual trunk and extension

ports, however, if this configuration is uploaded to a system it may be necessary to initialise

command 10-42-01 to 0 and then re-assign the required number of loopback ports. Care should,

therefore, be taken to ensure that all relevant ports are reassigned accordingly.
