Hello,
I see – do you get any error message in the logs? Can you execute it with debug logging activated, the function should output some debug logs about its working.
Cheers,
Henning

Thank you for your response Henning!
Unfortunately, it is not removed from outgoing message.
True. I also believe that msg_apply_changes is not recommended, hence I am not using that.
Thank you,
Mitesh

Hello,
does it actually remove the media after you send the message out? Usually the message altering functions will only be applied when you send out the message due to performance reasons.
You can force it in the cfg with the function “msg_apply_changes” – then you should be able to see it as well in the log. But using this function has other side effects and is not recommended if you don’t need it.
Cheers,
Henning

Hi,
I wants to remove media type "image" from SDP. For that I have tried to use KSR.sdpops.remove_media but it is not working. Not working in the sense that there is no effect of that function on SDP. I am using lua. Kindly find more details below.
Kamailio version: kamailio 5.2.5 (x86_64/linux) 62d35f
SDP to process:
INVITE sip:xxxxxxxxxx@xxxxxxxxx.com:5060 SIP/2.0

Code snippet:
KSR.sdpops.remove_media("image")
logger.log("info", "SDP:" .. headers.get("$sdp(body)"))
Log snippet:
One more thing I would like to mention that if I do not use dialog module then the function KSR.sdpops.remove_media works. But I can not avoid using dialog module.
Thanks in advance.
