Just discovered an acc parameter which does the trick and suppresses ACK accounting:modparam("acc", "report_ack", 0)Sorry for not reading properly.Still I am confused why radius receives start records with ACK before INVITE start records.CheersGerry----- Original Message ----- From: "G.Jacobsen" g_jacobsen@yahoo.co.uk To: users@openser.org Sent: Wednesday, July 11, 2007 8:06 PM Subject: Radius - prevent start record for ACK ?

I am using freeradius with openser 1.0.1.

My problem is that openser is emitting TWO radius start records: One for

the

INVITE with SIP method = 1 (INVITE) and also a second start record for SIP Method = 4 (ACK)

Is is normal that a start record is also emitted for the ACK ?

As long as the INVITE record is sent before the ACK record that is no

real

problem.

However every-now-and-then (no pattern observed) Openser sends the Radius start record with SIP Method = 4 (ACK) before the Record with SIP Method =

1

for the INVITE.

The problem is that the Radius record for the ACK does not contain the username from the credentials so that the username is not correctly set in the Radius record, instead of the correct username the callerid is used

as

the username.

How do I prevent that openser sends start records for the ACK ? Quite frankly I do not understand why a start record for ACK is emitted since I set the radius_flag only for INVITEs.

the relevant parts from my configuration:

modparam("acc", "radius_config", "/usr/local/etc/radiusclient-ng/radiusclient.conf") modparam("acc", "radius_flag", 1) modparam("acc", "log_flag", 1) modparam("acc", "service_type", 15)

route{

..... # If this is an INVITE and not RE-INVITE start accounting if(is_method("INVITE") && !has_totag()){ # set the acc flags setflag(1); };

    if (is_method("ACK")) { #hop-by-hop ACKs are absorbed here
            t_newtran();
            # drop broken ACKs
            exit;
    };

Any hints are welcome.

TIA

Gerry
