[Serusers] Re: radius accounting - sr-users

Even though your second record says that it is Sip-Method = Bye, it
really is ACK.  The provided sip_dictionary does not match what SER is
sending.

Sip_dictionary says:

VALUE           Sip-Method              Other                   0
VALUE           Sip-Method              Invite                  1
VALUE           Sip-Method              Cancel                  2
VALUE           Sip-Method              Ack                     3
VALUE           Sip-Method              Bye                     4

But SER is actually using (msg_parser.h):

enum request_method { METHOD_UNDEF=0, METHOD_INVITE=1, METHOD_CANCEL=2,
METHOD_ACK=4,
        METHOD_BYE=8, METHOD_OTHER=16 };

Notice that 4 in the dictionary is Bye, but in msg_parser.h it is Ack.
Also notice that you receive a 3rd RADIUS accounting message with
Sip-Method = 8.  That is the real BYE.  So change sip_dictionary to:

VALUE           Sip-Method              Undefined               0
VALUE           Sip-Method              Invite                  1
VALUE           Sip-Method              Cancel                  2
VALUE           Sip-Method              Ack                     4
VALUE           Sip-Method              Bye                     8
VALUE           Sip-Method              Other                   16

If you want to eliminate the ACK radius records add this to ser.cfg:

modparam("acc", "report_ack", 0)

I have yet to see a situation where the ACK record is different from
than the INVITE, other than the Sip-method type.  I'm puzzled as to why
they send it.

Hope that helps.

  Is Sip-Method set to ACK in one of the start records ?

   Jan. 
NO. 

I have two consecutive starts with:
Sip-Method = Invite
and
Sip-Method = Bye 

and one stop with
Sip-Method = 8
