Hi Daniel,
No I have not used the below line in my config file. I just asked do we need
this as well?
modparam("siptrace", "traced_user_avp", "$avp(traced_user)")
Am using sip_trace() function call in route and onreply_route logic.
My config for siptrace module:
modparam("siptrace", "db_url","mysql://opensips:opensipsrw@localhost/opensips")
modparam("siptrace", "duplicate_uri", "sip:****remoteip***")
modparam("siptrace", "duplicate_with_hep", 1)
modparam("siptrace", "trace_to_database", 0)
modparam("siptrace", "trace_flag", 22)
modparam("siptrace", "trace_on", 1)
modparam("siptrace", "hep_version", 2)
route{
$avp(traced_user) = "1";
sip_trace();
……
}
So I have added the line you mentioned in my opensips.cfg file. Will this
itself work not returning AVP as NULL?
Regards,
Agalya

Hi Agalya
So every time when we use ‘siptrace’ module we need to give some value for
$avp(traced_user) right?
The simple answer is YES.
When you defined this:
modparam("siptrace", "traced_user_avp", "$avp(traced_user)") also in the config
file?
You are telling siptrace module to trace calls that have this AVP with some
kind of value. This value will also be written to the table if you storing the
siptrace.
Also you need to call trace_dialog() or sip_trace(), depends on your scenario.

Am I understanding it right?
Just adding the line $avp(traced_user) = "1"; in config file will solve the
issue? Or we need to include
modparam("siptrace", "traced_user_avp", "$avp(traced_user)") also in the config
file?

Correcting:
$avp(traced_user) = "1";

Hi
AVP is a kind of variable on Opensips.
When you configured the siptrace module to use the AVP, you must ensure that
the AVP has some kind of value before routing the package, otherwise it will be
NULL. Just add this on first line of main route:
$avp(traced_user) = 1;

Subject: [OpenSIPS-Users] Query about avp in siptrace module
Hi,
Am Agalya and we are using opensips for our project and using “siptrace” module
to trace and duplicate the sip packets to another server.
When trying to do so, am getting the below error.
Mar 2 14:48:21 poc-opensip-cmc-e-001 /usr/local/sbin/opensips[27754]:
DBG:siptrace:trace_onreq_in: trace on req in
Mar 2 14:48:21 poc-opensip-cmc-e-001 /usr/local/sbin/opensips[27754]:
DBG:siptrace:trace_onreq_in: nothing to trace...
I thought adding “traced_user_avp” parameter might solve the issue. I have
added the below line and tested the same.
But I didn’t get through the error and was still seeing the same error.
modparam("siptrace", "traced_user_avp", "$avp(traced_user)")
As a workaround, I commented the below lines in “siptrace.c” file in function
trace_onreq_in(), and it worked for me.
Packets are sent to another server. Following the same I have commented the
same line of code wherever it is failing for me.
By adding some debugging statements I found AVP is NULL and
(!flag_trace_is_set(msg)) returns 1.
/*if( (avp==NULL) && !flag_trace_is_set(msg))
{
LM_DBG("nothing to trace...\n");
return;
}*/
Query : What is avp? And when avp is returned NULL?
What should I do in order to avoid that error without
commenting the code?
Why is “traced_user_avp” parameter is used in config file?
It would be great if you help me to come out of this issue. Also am curious
what causes this error message.
Regards,
Agalya
