Hello Daniel,

it works now:

0(22097) DEBUG: <core> [sr_module.c:625]: find_export_record: found <bind_textops> in module textops [/usr/lib/kamailio/modules_k/textops.so]

Thanks!

We are going to add some functionality to the siptrace module concerning distributed logging without writing the data to your local database. When using trace_send_duplicate we loose the information from fromip_column, toip_column and direction_column as well as the exact time. So we need to send this information, too. We have two approaches.

First approach:

Instead of writing the data to the local database send all the database fields in one udp paket to another server and write them into database there.

Second approach:

Add 4 header fields containing the information to the sip-message and send the SIP message to another Kamailio server using trace_send_duplicate. There remove the 4 Header fields and write into the database.

Do you think there is a better way to achieve this?

Kind regards

Timo Klecker

Betreff: Re: [SR-Users] Problem using textops API

Hello,

probably it was forgotten to export the internal API bind function. I just committed the fix on GIT master branch (devel version):

http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=db188fbcf4d752a2afab2e298a2f081f836d7e92

I couldn't test it for now, so if you can give it a try and report whether it is working ok or not, then I can backport the fix to 3.1.

Thanks,
Daniel

Hi,

I’m trying to extend a Kamailio Module and need to add and remove headers in a SIP Message. To do this I want to use the textops module and I am importing the api and trying to bind the textops module.

#include "../textops/api.h"

[..]

struct textops_binds tob;

[..]

/* register callbacks to TEXTOPS */

if (load_textops_api(&tob)!=0)

{

                LM_ERR("can't load textops api. Is module textops loaded?\n");

                return -1;

}

Later I use tob.append_hf to add a header field.

Everything compiles fine but on Kamailio startup there is a Error Message:

I am running Kamailio 3.1.4.

Is this a bug in Kamailio or am I doing anything wrong in my approach to use textops?

Kind regards,
