LAR doesn't trigger on 503 Service Unavailable
 
Scenario


remote site ( G450 MG ) connected to Main

Users ( remote site) calls over SIP trunks ( Configured on Main server) and sometimes gets busy. It is an intermittent issue. Route pattern has 3 trunk-groups in preference, first 2 SIP trunks and 3rd one Local PSTN. So if channels of first trunk-group are busy,LAR should trigger and call should go over 2nd trunk-group in preference .But it is not happening.

i kept LAR value 'next' now. What else we should look for.

Trace shows

503 Service Unavailable , temporary Failure denial event 1192...
