Interactions

■ Automatic Circuit Assurance

LAR rerouting attempts are recorded as short holding time calls.

■ Distributed Communications Systems (DCS)

If a non-DCS trunk preference is selected for rerouting a DCS call, DCS

feature transparency is lost. If LAR for a DCS call is done within the same

DCS trunk group, feature transparency is not lost.

■ QSIG Networks

If a non-Supplementary Services B (SSB) trunk preference is selected for

rerouting a SSB call, QSIG feature transparency is lost. If LAR for a QSIG

call is done through either the same or another SS B trunk group, feature

transparency is not lost.

■ Ringback Queuing

When a call originates and queues at the trunk group queue, the call can be

placed in queue multiple times if LAR is active. The call originator can be

called back each time the call is continued automatically.

■ Satellite Hop Limit

Satellite Hop Limit always takes precedence over LAR. When the

maximum hop limit is reached for a route preference, the last call routing

attempt is denied and the call is rejected with a cause value of #28 —

invalid number format. This value does not activate LAR.

■ System Measurements

System resource use during LAR attempts are included in existing system

measurements and performance reports. For more information about LAR

system measurements, see Reports for Avaya MultiVantage™ Software.
