Handling Process

1.Login U1981 by LMT tool,test and capture call log.The module need choose CCM,USAM,CM,RM,VU,PRI,SIP,SIPTK

2.According to the call log analysis, the reason for this problem is the use of the same PRA trunk by the incoming and outgoing call.

3.Type commend: "Config softargu  type  334 value 0" to modify softargu 334

4.The issue still exist. Test and capture call log again

5.According to the new call log, the reason of this problem is insufficient outgoing call authority of PRI trunk(trunkgroup 2 ), it just has inter/local outgoing call authority. But 0571203334's prefix is DDD. So need add DDD outgoing call authority on the PRI trunk(trunkgroup 2 ).
