[OpenSIPS-Users] Latest AVP's in the cdr when call fails in branch

[Pat Burke]

Hi Bogdan,


I got it figured out.  It was a series of configuration issues and not realizing how some of the new cdr process worked.  


1)  The branching was just bad timing on my part.  It is working fine.  The issue I saw just happened to be after I implemented branching.


2) The real issue was in the call to do_accouting, I set the cdr and missed_call flags, but not the failed flag.


Where I got confused was that the acc table had the correct record when the call completed successfully.  If there was an error and the call didn't complete successfully, there was a record in the missed_call table that didn't have the final avp values.   I did notice that after putting the failed flag in place and having a call fail, the acc record is correct (contains the lastest avp values)  but the missed_call record does not contain all of the lastest avp values.




I do have one more question on the migration from 1.11 to 2.2.


        In  1.11 we had the following set
             modparam("dispatcher", "flags", 2)
             modparam("dispatcher", "force_dst", 1)


        in 2.2, I use the following in 
             ds_select_dst("$var(server_group_carrier_setid)","6","FS")


Do I have the parameters correct in the ds_select_dst call?


Thanks,
Pat

Hi Pat,

It is a bit confusion and the most of the report is about adding an AVP as hdr via append_hf() , but you also mention something about CDR...and I do not see the relation between the two.

First of all, is the append_hf() working fine ? is the header (in the sequential attempts) containing the correct aggregated value ?

Hello,


I am in process of migrating from 1.11 to 2.2.  We have a situation where we have a routing opensips that can make multiple attempts to complete a call.  The information specific to each attempt is passed to the SBC opensips through headers.  In order to not double up on headers, I moved the code that calls append_hf to a branch.  As the call progresses, I update various AVP's and print them into the log (so I can see that they are being updated correctly).  Below is an example scenario of what I am doing.






initial call setup logic
set the t_on_failure


setup for first carrier 
branch 
   setup headers with carrier information used by the SBC
   $avp(test) := "Step 1;";
t_relay


on_failure (for example 480 - timeout)
   setup for the next carrier
   branch
      setup header for next carrier information used by the SBC
      $avp(test) := $avp(test) + "Step 2;";  # avp(test) now equal "Step 1;Step 2;"
t_relay



on_failure (for example 408 - timeout)
   no more carriers, end the call






What gets put into the cdr is "Step 1;" not "Step 1;Step 2;"


Also, the sip_code is set to the first failure received from the SBC, not the last.


If the call completes successfully, the cdr data is correct.


Thanks,
Pat Burke
