Hello,

Attached is a patch that implements "swap_direction" parameter of acc
module. If you turn the parameter on in the configuration file:

modparam("acc", "swap_direction", 1)

then the acc module will swap Calling-Station-ID and Called-Station-ID
values when necessary (in this case BYE comming from the callee).

Put the patch in top level source directory (ser-0.9.x) and type:
patch -p0 < swap.patch

The patch should work with any 0.9.x release.

Note that Alan DeKok is wrong in thinking that this is a bug in SER.
This particular problem is a result of incomplete specification of
RADIUS use with SIP. I will commit the patch in CVS so it will be
included in future SER releases.

  To me the Calling-Station-Id and the
Called-Station-Id should be the 
 same for both start and stop records, am I right by thinking that?  
   Yes.

  According to the developers of SER/OpenSER, this
is the correct 
 behavior, whoever sends the hangup signal (BYE or CANCEL) is 
 considered the Calling-Station-Id, and they are unwilling to modify or 
 create a patch to "fix" this.  
   What they do for something inside of SER is their business.  When they
 generate RADIUS packets, they should follow RADIUS standards and
 interoperability.  The expectation, as you said, is that the
 Calling/Called-Station-Id doesn't change during a session.  If it does, it's
 a bug and they should fix it.

you never can anticipate
 who hangs up the call, thus radius wont know who hung up the  call...Besides
  all other voice applications/hardware (SIP and
H323) that use radius do  not
  behave like that, the Called-Station-ID ALWAYS
remains the same, as with  the
  Calling-Station-ID.  
   Could you name those SIP applications that behave the way you describe ?
