Hello Daniel,

Returning to this issue(I didn't have enough time before, to continue with debug),  I have configured the module debugger, in order to try see more information when kamailio executes the function "sdp remove codecs_by_id",  and what i see is that the function is executed and  the logs  says that the function removes the codecs specified in SDP body, but in reality it doesn't happen, and there isn't any errors executing the function.

Please have a look at the logs below:

Hello,

I added the following xlog before function

xlog("L_INFO", "[SDPOPS] executing function sdp_remove_codecs_by_id($avp(s:codecs_to_remove)) ID=$ci\n");

and if i have set debug=2 I can see the xlog message, if I change it to 3 I cannot see my message, even if I set xlog with L_DBG i cannot see the message in syslog, this is a weird behavior, can be something wrong with my rsyslog service?

I did a test that was edit the c function sdp_remove_codecs_by_id in sdpops_mod.c and i changed the log message from LM_DBG to LM_INFO, then i compiled and ran again the test and i can see the internal log messages from function sdp_remove_codecs_by_id.

syslog:

Hello,

can you enable cfgtrace via debugger module or add an xlog just before calling the function in configuration file and see if related message appears in syslog?

Cheers,
Daniel

Hello,
Thank you for your reply

I ran kamailio with debug=3 and log_stderror=yes and the only thing that i see related with function  sdp_remove_codecs_by_id is:

 0(4707) DEBUG: <core> [route.c:907]: fix_actions(): fixing sdp_remove_codecs_by_id()


if i set  debug=3 and log_stderror=no then i look for syslog file where kamailio is writting logs, and i don't see anything related with function sdp_remove_codecs_by_id.

I'm not using msg_apply_changes function.

Thank you for your support

Hello,

I'm using the function sdp_remove_codecs_by_id from sdpops module in order to remove some codecs in INVITE request before send  it to freeswitch, but the function doesn't remove the codec, and it doesn't give any error message.

I'm using this function in request route.
