[OpenSER-Users] Trouble with RADIUS Accounting

[Dmitry Lyubimkov]

Ok. It's work.

        User-Name = "sip:loft at voapp.com"

        Called-Station-Id = "sip:769101 at voapp.com"

        Calling-Station-Id = "sip:loft at voapp.com"

 

But there is the same problem as in early version of OpenSER. Field
User-Name depend on who hang-up the call. In case of A call B in Start
record we receive right User-Name=A, Calling=A, Called=B. But if B hang up
first then in Stop record we'll receive User-Name=B, Calling=B, Called=A. It
is difficult to manipulate fields in some RADIUS servers. I think that

modparam("acc", "detect_direction", 1)

helps to resolve this problem now. But if we receive RADIUS field through
modparam("acc", "radius_extra", "...   command we can use only pseudo
variables and avp. And there is no variable for Invite username. And AVP
(pv_printf("$avp(username)", "$au at voapp.com");) exists only on Invite. When
we receive BYE this AVP will be empty because AVPs are persistent per SIP
transaction only.

 

Can we somehow get initial (from INVITE) UserA and UserB for Stop RADIUS
messages in BYE processing stage?

Hi Dmitry,

starting of 1.2 version OpenSER does not add anymore any attribute
automatically, you must instead add your wishlist manually with radius_extra
parameter:
http://www.openser.org/docs/modules/1.3.x/acc.html#AEN319

An example of config:

modparam("acc", "radius_extra", "
                                        Called-Station-Id=$tu;
                                        Calling-Station-Id=$fu;
 
Canonical-URI=$(avp(s:canonical_uri));
                                        User-Name=$fu;
                                        Sip-User-Realm=$ar;
                                        Source-IP=$si;
                                        Source-Port=$sp;
                                        Acct-Authentic=$(avp(s:authentic));
                                        From-Header=$(hdr(from));
                                        User-Agent=$(hdr(user-agent));
                                        Contact=$(hdr(contact));
                                        Event=$(hdr(event))
                                        ")

Cheers,

But we did it!!! I don't need to remove this attributes. We need User-Name,
Called-Station-Id, Calling-Station-Id, etc for billing purpose. But our
RADIUS server does not receive them from OpenSER! Look at our Start/Stop
messages. There are not such important attributes as User-Name, etc.
Is this bug of OpenSER or bug of our script? If it is bug of script, then
what commands, what modules, what modparam can lead to such result?

Hi Dmitry

You not can remove them from OpenSER with out adjusting the code,
instead you need to put the radius packets thought something like a
radius proxy which removes them.
