Re: CallId is not the same for authentication and accounting.

The problem is that for this endpoint the  callIdentifier  in ARQ  is different from the one sent in Setup.

From ARQ:
...
...
callIdentifier = {
      guid =  16 octets {
        cb 52 bd 78 49 fe 18 10  81 ea 00 11 43 04 d8 76   .R.xI.......C..v
      }
    }

...

q931pdu:
...
...
   callIdentifier = {
          guid =  16 octets {
            4f 71 bd 78 49 fe 18 10  81 eb 00 11 43 04 d8 76   Oq.xI.......C..v
          }

 }
...
...

Since I cannot change this endpoint, I would like to move my authentication and routing to setup but  I'm still figuring out how to implement that. I would like to  skip the routing during ARQ as I explained in my earlier email below.

Any help will be appreciated.
thnx,
Nour.

Jan,
This was NOT happening for all the calls, I found it was happening for one endpoint. I will send you the traces.
In the mean, I was wondering if there is away I can skip authentication in ARQ and authenticate Setup instead. My callers are always registered but the called are mostly external telephone numbers routed from db during SqlAuth authentication.   If Iremove ARQ authentication(or I did simple  sqlauth authentication that returns 1) , the call fails with an error saying "CalledPartyNotRegistered" this happens before setup. 
So I was wondering a workaround this.
Thanks,

Hi,

this is certainly not the expected behavior. The CallID is supposed to
be the same for authentication and accounting. (It is actually expected
to be globally unique, but I wouldn't totally count on that.)

The CallID is taken from the messages the endpoints send. Did you check
in a trace if the endpoints always send the same CallID ?

Regards,
Jan
