Issue Description
Product: ATS9900
Version: V100R003C00SPC100
[Symptom] A# is centrex subscribers. He dialed centrex outgoing-prefix; “9” and area code+full number (04-xxxxxxx); 04 is area code. The B party in CDR becomes double area code.
CDR 1 example:
                           Record-Type  =  {ATS}
                        Retransmission  =  {FALSE}
                            SIP-Method  =  {BYE}
                          Role-Of-Node  =  {ORIGINATING_ROLE}
                          Node-Address  =  {sjaatshw01.ims.tm.com.my}
                            Session-ID  =  {6oscfmmlgcllc5yfyp25qpstl6ln2rnr@UAC}
         List-Of-Calling-Party-Address  =  {{tel:+6045983120}}
                  Called-Party-Address  =  {tel:+604045982710}
            Service-Request-Time-Stamp  =  {2011-09-07 11:40:32+08:00}
     Service-Delivery-Start-Time-Stamp  =  {2011-09-07 11:40:47+08:00}
       Service-Delivery-End-Time-Stamp  =  {2011-09-07 11:41:35+08:00}
Alarm Information
Null
Handling Process
One more configuration for this prefix 04 as following needed, otherwise ATS will insert the area code into the dialed number.
ADD DNC:DCX=2,DCT=DEL,DCP=0,DCL=2,DAI=NONE;
ADD PFXPRO:CALLSC=467,LOCALP=467,PFX=K'04,NCAI=ALL,CLDCF=TRUE,SSM=NST,FPF=FALSE,CLRCF=FALSE,NP=255,NLP=65535,RDCX=0,DDCX=2,REANA=TRUE,TT=0,ANAITM=CODEC-0&SRVPRO-0,FCC=NSSC;
 
Notes:
Add number change to delete 2 digits in the called number.
Add call prefix processing for related callsrc and ldnset and prefix “04” to apply the number change.
Root Cause
From ATS trace msg, in DN_ANALYSIS, the service property was configured as sp-intraoffice. In current version of IMS8.0, the relationship of the called number is tightly coupled with the configuration of CNACLD.
ADD CNACLD:LOCNUM=467,URISCH=TEL_URI,PFXCDE=K'04,CSTP=BASE,CSA=LCO,CUSTA=NULL,MINL=2,MAXL=32,TOLLPF=FALSE,RDT=0,ANTIP=0,SPCHG=FALSE,SPCDAF=FALSE,CLRAF=FALSE,PQRL=2,OWNEX=FALSE,
PRKEX=FALSE,EMCF=FALSE,UNIFTYPE=UNIFORM_WITH_SEP,BILUNIFTYPE=UNIFORM_WITHNO_SEP,SENDTYPE=Unsupport_overlap,CHSC=65535,PREPFLG=YES,RM=RPCTRL,RESERVED=0;
