Re: [SR-Users] KSR.sdpops.remove_media is not working as expected

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.

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.

But I can not avoid using dialog module. Thanks in advance. Mitesh
